Question

What is the quotient of 1, point, 7, 2, 8, times, 10, to the power 91.728×10
9
and 4, point, 8, times, 10, to the power 64.8×10
6
expressed in scientific notation?

Answer 1

Interpret the numbers as 1.728×10^(91.728×10^9) and 4.8×10^(64.8×10^6). Then

Quotient = (1.728/4.8) × 10^(91.728×10^9 − 64.8×10^6)
= 0.36 × 10^(91,728,000,000 − 64,800,000)
= 0.36 × 10^91,663,200,000
= 3.6 × 10^91,663,199,999.

So the result in scientific notation is 3.6 × 10^91,663,199,999.
