A. Add 3.2 x 10^4 and 1.95 x 10^6

Answer 1

To add 3.2 x 10^4 and 1.95 x 10^6, we first need to ensure that the exponents are the same. In this case, both numbers are already in scientific notation with the same base (10), so we can proceed with the addition.

Step 1: Add the coefficients:
3.2 + 1.95 = 5.15

Step 2: Keep the base (10) and add the exponents:
10^4 + 10^6 = 10^6

Therefore, the sum is 5.15 x 10^6.
