Work Step by Step

1. Rearrange the numbers to make it easier for multiplication and division: $[\frac{1.36 \times 10^{5} \times 0.000322}{0.082}] \times 129.2 = \frac{1.36 \times 10^{5} \times 3.22 \times 10^{-4}}{8.2 \times 10^{-2}} \times 1.292 \times 10^{2} = 6.899 \times 10^{4} = 6.9 \times 10^{4}$
