Question

What is the quotient of 3.91×10 to the power of 7 and 2.3×10 to the power of 2 expressed in scientific notation?

Answer 1

To find the quotient of these numbers, we divide the numbers and then divide the powers of 10.

(3.91 x 10^7) ÷ (2.3 x 10^2) = (3.91 ÷ 2.3) x 10^(7-2)
= 1.7 x 10^5

Therefore, the quotient of 3.91×10 to the power of 7 and 2.3×10 to the power of 2 expressed in scientific notation is 1.7 x 10^5.
