Divide in scientific notation quick check

Answer 1

To divide numbers in scientific notation, follow these steps:

1. Divide the coefficients (the numbers that come before the 10 raised to a power).
2. Subtract the exponents (the powers of 10).
3. Put the new coefficient over 10 raised to the new exponent.

For example, let's divide (3.2 x 10^4) by (8 x 10^2):

1. Divide the coefficients: 3.2 ÷ 8 = 0.4.
2. Subtract the exponents: 4 - 2 = 2.
3. Write the new coefficient over 10 raised to the new exponent: 0.4 x 10^2.

Therefore, (3.2 x 10^4) ÷ (8 x 10^2) is equal to 0.4 x 10^2.
