What rules do we use to convert standard to scientific notation?
Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!
How do you write 6000 in scientific notation?
When Writing 6000 in scientific notation, we must first count the decimal places from the right side of the number going to the left then multiplied by 10 raised to the number of decimal places. So to write 6000 in scientific notation: Answer:6.0x103 Because since there are 3 decimal places going to the right multiplied by 10 and raised to the number of decimal places.Likewise if 0.00006 is expressed in sci.(scientific) notation we write it as: Answer:6x10-4 Rule: If the decimal point goes to the left, the exponent is positive but if it goes to the left,the exponent is negative
What is the correct powers of ten notation for the value 483.54 with three significant figures?
To three significant figure, 483.54 becomes 484. The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". Expressed in Scientific Notation, 484 becomes 4.84 x 102.
What are the rules in adding subtracting multiplying dividing scientific notation?
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 NotationMultiplication 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.
What is a general rule for two integers with the same sign?
The general rule is that they are both on the same side of zero on the number line.
