Question

(8.3*10^2)*(9.1*10^-7)

Please help me solve this result in scientific notation.

Answer 1

(8.3*9.1) 10^(2-7)

Answer 2

i got 75.53 for the first half, but for the second half i got -50, and that doesn't seem right.

Answer 3

Huh?
10^(2-7) = 10^-5
Try
75.53 * 10^-5

However you started with only 2 significant figures in each number so
76 * 10^-5

Answer 4

Ok Thank You!

Answer 5
