Question

4.1 x 103 ) x (1.6 x 10-2) = a.6.56 x 10 b.6.56 x 105 c.6.56 x 10-5 d.656 x 101

Answer 1

Option A

6.56 x 10

Explanation:

To solve this problem we will apply the laws of indices.

`(4.1 * 10^(3)) * (1.6 * 10^(-2))`

One of the law states that when you are multiplying powers which have the same base, you are expected to add the powers together.

This means our answer will be
`(4.1 * 1.6 ) * (10^((3-2)))`

if we multiply 4.1 by 1.6, we will get 6.56.

If we subtract 3 -2 we will get 1.

Therefore our answer will be
`6.56 * 10^1` Option A
