Exercise 47 Page 476

Recall the Property for Dividing Powers with the Same Base.

2.5* 10^2

Practice makes perfect

We want to simplify the given quotient and express it in scientific notation. To do so, we will apply the Property for Dividing Powers With the Same Base.
a^m/a^n = a^(m-n) The above property is valid when a≠ 0 and when m and n are both rational numbers. Let's do it!

3.1* 10^4/1.24* 10^2
WriteProdFrac

Write as a product of fractions

3.1/1.24 * 10^4/10^2
DivPow

a^m/a^n= a^(m-n)

3.1/1.24 * 10^(4-2)
SubTerm

Subtract term

3.1/1.24 * 10^2
CalcQuot

Calculate quotient

2.5* 10^2

Note that we do not want to continue multiplying or simplifying, because the simplified expression is now written in proper scientific notation.
