To add these two numbers together, we first need to convert them to the same base.
7.35 x 10^-7 = 0.000000735
2.16 x 10^-8 = 0.0000000216
Adding these two numbers together, we get:
0.000000735 + 0.0000000216 = 0.0000007566
Therefore, 7.35 x 10^-7 + 2.16 x 10^-8 = 7.566 x 10^-7.
3. 7.35 x 10^-7 + 2.16 x 10^-8
