To add these numbers in scientific notation, we need to make sure that the exponents are the same.
First, let's write both numbers with the same exponent. We can do this by moving the decimal point in 3.2 × 10^4 two places to the right:
3.2 × 10^4 = 0.32 × 10^6
Now we can add the numbers:
0.32 × 10^6 + 1.95 × 10^6 = (0.32 + 1.95) × 10^6 = 2.27 × 10^6
So, the sum of 3.2 × 10^4 and 1.95 × 10^6 in scientific notation is 2.27 × 10^6.
