(1.5 x 10^-5) (3 x 10^2) express your answer in scientific notation

Sagot :

The given expression is

(1.5 x 10^-5) (3 x 10^2)

We would multiply the terms without the powers of 10 first. Then we would multiply the terms haveing the powers of 10 by applying the following rule

a^b * a^ c = a^(b + c)

Therefore,

1.5 * 3 = 4.5

10^-5 * 10^2 = 10^(- 5 + 2)

= 10^- 3

Therefore, the answer in scientific notation is

4.5 * 10^-3
