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

Answer:

Option A

6.56 x 10

Step-by-step explanation:

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

$(4.1 \times 10^{3}) \times (1.6 \times 10^{-2})$

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 $(4.1 \times 1.6 ) \times (10^{(3-2)})$

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 $6.56 \times 10^1$ Option A
