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

Mar 28, 2018

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

#### Explanation:

Changing the first term to a power of ${10}^{3}$

$17.65 \times {10}^{2} = 1.765 \times {10}^{3}$

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

$1.765 \times {10}^{3} + 1.625 \times {10}^{3} = 3.390 \times {10}^{3}$
