To add these two numbers, we need to have them in the same exponent form. Let's convert 2.56 x 10^-2 to scientific notation.
2.56 x 10^-2 = 0.0256 x 10^0
Now we can add the numbers:
3.2 x 10^4 + 0.0256 x 10^0
To add numbers in scientific notation, we add the coefficients and keep the same exponent:
3.2 + 0.0256 = 3.2256
Therefore, the sum of 3.2 x 10^4 + 2.56 x 10^-2 is 3.2256 x 10^4.
3.2 x 10^4 + 2.56 x 10^-2
