1,000,000,000 = 1 x 109 The rules of writing a number in this scientific notation are : M x 10N , where M is a rational decimal number between 0 and 10 and N is the Power of Ten it is raised to.
Addition and Subtraction in Scientific NotationA number written in scientific notation is written as the product of a number between 1 and 10 and a number that is a power of 10. That is, it is written as a quantity whose coefficient is between 1 and 10 and whose base is 10.Addition and SubtractionOne of the properties of quantities with exponents is that numbers with exponents can be added and subtracted only when they have the same base and exponent. Since all numbers in scientific notation have the same base (10), we need only worry about the exponents. To be added or subtracted, two numbers in scientific notation must be manipulated so that their bases have the same exponent--this will ensure that corresponding digits in their coefficients have the same place value.Multiplying a number by another number with the same base is equivalent to multiplying their coefficients and adding their exponents. Therefore, if we want to add two quantities written in scientific notation whose exponents do not match, we can simply write one of the powers of 10 as the product of two smaller powers of 10 , one of which agrees with the other term.Alternately, if we want to preserve the exponent of the term with the larger power of 10 , we can simultaneously multiply and divide the other term by a power of 10 , applying the rule for multiplication of exponents in one case and dividing the coefficient in the other. It is this procedure that we outline below. Once the numbers have the same base and exponents, we can add or subtract their coefficients.Here are the steps to adding or subtracting numbers in scientific notation :1. Determine the number by which to increase the smaller exponent by so it is equal to the larger exponent.2. Increase the smaller exponent by this number and move the decimal point of the number with the smaller exponent to the left the same number of places. (i.e. divide by the appropriate power of 10 .)3. Add or subtract the new coefficients.4. If the answer is not in scientific notation (i.e. if the coefficient is not between 1 and 10) convert it to scientific notation.Multiplication and Division in Scientific Notation Multiplication and DivisionQuantities with exponents can be multiplied and divided easily if they have the same base. Since all number in scientific notation have base 10 , we can always multiply them and divide them.To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents. In either case, the answer must be converted to scientific notation.Here are the steps to multiply two numbers in scientific notation:1. Multiply the coefficients--round to the number of significant figures in the coefficient with the smallest number of significant figures.2. Add the exponents.3. Convert the result to scientific notation.Here are the steps to divide two numbers in scientific notation:1. Divide the coefficients--round to the number of significant figures in the coefficient with the smallest number of significant figures.2. Subtract the exponents.3. Convert the result to scientific notation.
The answer depends on the context. There are rules for sequences, rules for regression, rules for scientific laws to name a few examples.
One hundred thousand in Scientific notation is 1x10^5, (^ meaning to the power of), therefore One hundred thousand to the power of ten is (1x10^5)^10 = 1x10^50, using basic rules of powers or 1 followed by 50 zeros.
This notation will be assigned when the propulsion and essential auxiliary machinery has been constructed, installed and tested under Lloyd's Register's Special Survey in accordance with the Rules and Regulations. (LR Machinery Certificate).
In scientific notation all numbers are written in the form: a*10b where a is a decimal number such that 1 ≤ a < 10 and b is an integer.
When adding or subtracting numbers in scientific notation, ensure that the exponents are the same. If the exponents are not the same, adjust one or both numbers to match. Then, add or subtract the coefficients while keeping the exponent the same. Finally, simplify the result if necessary by converting it back to proper scientific notation.
In converting numbers into scientific notation, first you should move the decimal point such that there would be one significant figure to the left of the decimal point. Examples: 299792458 -> 2.99792458 0.0000000000667428 -> 6.67428 Then, count the number of times you moved the decimal point. Note the direction of movement. Examples: 299792458 -> 2.99792458 (8 digits to the left) 0.0000000000667428 -> 6.67428 (11 digits to the right) Lastly, express the number as a product of the modulus (the number with the decimal point moved) and a power of ten. Examples: 299792458 -> 2.99792458 x 108 (If the decimal point was moved to the left, the power is positive) 0.0000000000667428 -> 6.67428 x 10-11 (If the decimal point was moved to the right, the power is negative)
Move the decimal point to just after the first non-zero digit. The resulting number, a, will be the mantissa of the scientific notation.While moving the decimal point (dp), count the number of places, n, that decimal point has moved and whether it is to the right or left. If the dp was moved to the left, the exponent is 10a whereas if it was to the right the exponent is 10-a.Examples:234.567a = 2.34567, n = 2 (to the left) so 234.567 = 2.34567*102.0.00234a = 2.34, n = 3 to the right so 0.00234 = 2.34*10-3.
20,000 + 3,400,000
The easiest way to convert is using scientific notation. For example, 0.025A is equal to 2.5 * 10^-2. Since 1 MA is equal to 1 * 10^6 and you're converting up, subtract the larger notation and you end up with 2.5 * 10^-8. Converting from scientific notation back to decimal form means moving the decimal point over the same number of times as the power of 10, so you'd have .25 preceded by 7 zeros (we already moved it over one), or .000000025 MA. Most people prefer to use the scientific notation because its easier to work with once you learn the rules of powers, and there is more room for error when you are counting zeros.
Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!
0.72 in Scientific Notation = 7.2 x 10-1Scientific notation is always written in the form a x10b. When b is positive, it shifts the decimal point to the right and when it is negative, the decimal point shifts to the left (when converting back to decimal form). See the link below for a full explanation.
I don't know what you mean "how to write the rules." In the US, "standard" notation means "long form", i.e. 6,000,000, while "scientific" notation means the exponential form, 6x106. I had thought it was the same in the UK, but Mehtamatics says otherwise: "Standard notation and scientific notation are the same in terms of UK usage of these phrases."

Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive). a is called the mantissa and b is called the exponent. To convert a number to scientific notation:If the number has no decimal point, then add one at the end.Then move the decimal point to just after the first non-zero digit while counting the number of places you have moved it.The mantissa of the new number, formed after moving the decimal point is a.If the original number is negative, then so is a.The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.There is no sixth rule.
First, you have to line up the decimal places by converting the smaller number to the same exponent as the larger number. Then you can subtract them in the obvious way. For example, 3.78 x 105 - 4.61 x 103 = 3.78 x 105 - 0.0461 x 105 = 3.7339 x 105, because 4.61 x 103 = 0.461 x 104 = 0.0461 x 105.
