6.33 × 10^6+ 4.13 × 10^6

1 answer

To add these two numbers in scientific notation, we need to make sure the exponents are the same.

6.33 × 10^6 + 4.13 × 10^6 = (6.33 + 4.13) × 10^6 = 10.46 × 10^6

Here, we have a number between 1 and 10, so we can rewrite this as:

10.46 × 10^6 = 1.046 × 10^(6+1) = 1.046 × 10^7

Therefore, 6.33 × 10^6 + 4.13 × 10^6 = 1.046 × 10^7.
