Question

Which shows the expression below simplified?0.00033 + (2.1 x 10-6)A.3.321 x 10-4B.2.10033 * 10-10C. 2.10033 x 10-6D.3.321 x 10-6

Answer 1

A

Explanation:

We are given the following expression:

0.00033 + 2.1*10^-6

We have to place them in the same base.

Trying the problem options:

10^(-4)

0.00033 = 3.3 * 10^(-4)

2.1*10^(-6) = 0.021 * 10^(-4)

The sum is: 3.321 * 10^(-4)

Option A is the answer
