Question

Which expression is equivalent to rm ÷ rn? (4 points)

Answer 1

By applying the exponent rule of division, the equivalent expression to  $r^m \div r^n$ is: A. $r^{m - n}$.

How to Determine Equivalent Expressions?

Given the expression, $r^m \div r^n$, we can find the expression that is equivalent to it by rewriting the expression as shown below:

r^m ÷ r^n

According to the exponent rule of division, if we are to divide two bases together that have the same same base but different exponents, what we only need to do is to subtract their powers.

We would apply this same rule in this given problem.

Applying the exponents rule of division, we would subtract the powers:

r^m ÷ r^n = r^(m - n)

Therefore, by applying the exponent rule of division, the equivalent expression to  $r^m \div r^n$ is: A. $r^{m - n}$.
