How do you divide and multiply in scientific notation?

How do you divide and multiply in scientific notation?

“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.”

How do you multiply by 6.02 x10 23?

“Calculate 10 to the power of 23 and get 100000000000000000000000. Multiply 6.02 and 100000000000000000000000 to get 602000000000000000000000.”

Can you multiply scientific notation with a whole number?

“Multiply the whole number by the coefficient of the number in scientific notation. For example, if you want to multiply 2.5 * 10^3 by 6, multiply 2.5 by 6 to get 15.”

How to multiply scientific notation with negative and positive exponents?

““

What are the 4 rules of scientific notation?

“The base should be always 10. The exponent must be a non-zero integer, that means it can be either positive or negative. The absolute value of the coefficient is greater than or equal to 1 but it should be less than 10. Coefficients can be positive or negative numbers including whole and decimal numbers.”

How do you solve multiplication exponents?

“When you’re multiplying exponents, use the first rule: add powers together when multiplying like bases. 5^2 × 5^6 = ? The bases of the equation stay the same, and the values of the exponents get added together.”
