The answer is: 7.79 x 10^7.
To simplify, you just subtract the coefficients:
(8.2 x 10^7) - (4.1 x 10^6) = 7.9 x 10^7
Then you put the answer in scientific notation by adjusting the decimal point and exponent to have only one non-zero digit before the decimal point (in this case, 7.9). However, you can't have a decimal point in scientific notation, so you adjust the exponent to compensate, which results in 7.79 x 10^7.
