Question

How do you add `17.65 x 10^2 + 1.625 x 10^3`?

Answer 1

Change both terms to the same power of ten and then add the significant digits.

Explanation:

Changing the first term to a power of `10^3`

`17.65 xx 10^2 = 1.765 xx 10^3`

Now since the terms are the same they can be added.

`1.765 xx 10^3 + 1.625 xx 10^3 = 3.390 xx 10^3`
