(3.2 x 10^-2) (4.2 x 10^6) / (5.2 x 10^5)

Answer 1

To solve this, we need to first simplify the expression by dividing the numbers and subtracting the exponents.

(3.2 x 10^-2) / (5.2 x 10^5) = (3.2 / 5.2) x 10^(-2-5) = 0.6154 x 10^-7

Then, we multiply this result by 4.2 x 10^6:

0.6154 x 10^-7 x 4.2 x 10^6 = 2.585 x 10^-1 = 0.2585

Therefore, the final result is 0.2585.
