How do you do exponential notation with negative exponents?
How to write them? ten to the minus three is 10^-3How to multiply them? add the exponents. Ex: 10^-3 x 10^-4 = 10^-7
How do we know if we have to multiply or add exponents if the bases are the same?
You have to add the exponents. It's best if you just remember it. You can also consider what happens when you multiply something like:(2 x 2 x 2) x (2 x 2) As you can notice, the number of factors get added. That's like adding the exponents.
What you do with the exponents when you you are multiplying?
If you are multiplying numbers with exponents, and the base is the same, you can just add exponents. For example, 104 x 105 = 109.
How do you write 67.5 billion in scientific notation?
To write 67.5 billion in scientific notation, we first need to move the decimal point to the right so that there is only one non-zero digit to the left of the decimal point. In this case, we would move the decimal point 10 places to the right, resulting in 6.75. Next, we express this number as a product of a number between 1 and 10 and a power of 10. Therefore, 67.5 billion in scientific notation is 6.75 x 10^10.
When dividing numbers in scientific notation what do you do with the exponents?
You subtract the exponent of the divisor from that of the dividend.

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.

How does scientific notation make it easier to perform computations with very large or small numbers?
In using scientific notation, you can use the number with the decimal to solve your problem and then factor in the power after the fact.
How do you add two scientific notation numbers together and come out with another scientific notation number?
You can add scientific notation numbers that have the same exponent. For example3 x 104 + 5 x 104 = 8 x 104If they don't have the same exponents, change one to match the other, then add:5 x 108 + 2 x 1075 x 108+ 0.2 x 108 = 5.2 x 108
Why do you need to rewrite the given scientific notation in the same power of 10?
If you are adding or subtracting two numbers in scientific notation the exponents must be the same before adding the coefficients. This is similar to 'like terms' in algebraic expressions. You can't add 5x3 and 3x2 because the exponents are not the same.
Rules in adding or subtracting scientific notation?
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.
How do you perform multiplication using scientific notation?
To perform multiplication using scientific notation you simply add the exponents after performing the multiplication of the values. Example: 32500 * 4521000 = ? 3.25 e4 * 4.521 e6 = 14.69325 e10 or 1.469325 e11
What are the rules of adding subtracting dividing and multiplying written in scientific notation?
1 With addition change the scientific notation back to 'normal numbers' and then add accordingly 2 With subtraction change the scientific back to 'normal numbers' and then subtract accordingly 3 With division subtract the exponents and divide the decimals 4 With multiplication add the exponents and multiply the decimals 5 Note that if changes occur below 1 or greater than 9 in the decimal element of the scientific notation then appropriate adjustments must be made
How do you you multiply in scientific notation?
Add the exponents and multiply the decimals as for example:- 2.5*10^4 times 3.75*10^3 = 9.375*10^7
When multiplying a number with exponents do you add or multiply the exponents?
You add exponents when multiplying. Ex: (xm) × (xn) = xm+n
How do you write the number 1329 x 10-7 in scientific notation?
1329 x 10-7 is equal to 1.329 X 103 X 10-7 When multiplying exponents you simply add them. So we have 1.329 X 10-4
