Question

Which expression is equivalent to rm ÷ rn??

Answer 1

I have worked that on paper

Answer 2

`r^(m-n)`

Explanation:

We have been given an expression
`r^m/ r^n`. We are asked to find equivalent expression to our given expression.

First of all, we will write our given division problem as a fraction:

`(r^m)/(r^n)`

Using exponent property
`(a^b)/(a^c)=a^(b-c)`, we can rewrite our given expression as:

`(r^m)/(r^n)=r^(m-n)`

Therefore, the expression
`r^(m-n)` is equivalent to our given expression.
