Answer: 3,500,000,000

Work Shown:

The x means "multiplication"

(7 x 10^2)(5 x 10^6)

(7 x 5)(10^2 x 10^6)

35 x 10^(2+6)

35 x 10^8

(3.5 x 10^1) x 10^8

3.5 x (10^1 x 10^8)

3.5 x 10^(1+8)

3.5 x 10^9

3,500,000,000

There are 8 zeros after the "3,5" portion.

This number is 3.5 billion. Another way to say it would be to say "3 billion, 500 million".

To go from the scientific notation 3.5 x 10^9 to the final answer, we move the decimal point 9 spaces to the right. If the exponent was negative, then we would move 9 spaces to the left.
