7.35 x 10^-7 + 2.16 x 10^-8

Answer 1

To add these numbers, we can first rewrite them in standard form:

7.35 x 10^-7 = 0.000000735
2.16 x 10^-8 = 0.0000000216

Now we can simply add these two numbers:

0.000000735 + 0.0000000216 = 0.0000007566

Therefore, 7.35 x 10^-7 + 2.16 x 10^-8 = 0.0000007566 in standard form.
