Find the simplified form of the expression. Give your answer iscientific notation. (9*10^5) (6*10^7)

The answer is 5.4*10^13.

9 x 10^5 * 6 x 10^7

First multiply 9*6 = 54

Second multiply powers of 10:

10^5 * 10^7 = 10^12

Putting it all back together we get 54 x 10^12.

This is not scientific notation because the decimal needs to be between the 5 and 4.

5.4 x 10^13
