Question

I'm not sure how to finish simplifying this problem.

1. (3 x 10^-2) - (6.2 x 10^1)
= (.003 x 10^1) - (6.2 x 10^1)
= -6.197 x 10^1 (need to make positive 'tween 1 and 10)

Answer 1

Correct result.

You also find result like that:

3 x 10 ^ - 2 = 3 / 10 ^ 2 = 0.03

6.2 x 10 ^ 1 = 6.2 x 10 = 62

3 x 10 ^ - 2 - 6.2 x 10 ^ 1 =

0.03 - 62 = - 61.97 = - 6.197 * 10 ^ 1
