Question

Find the equivalent number. (will mark the brainliest and youĺl be loved)

Answer 1

Answer:

B. 9

Step-by-step explanation:

So when solving a question like this, you may try to find what 3⁴ is and what 3² is and divide, but there is a much easier way to do this. Remember:

$\frac{a^{m}}{a^{n}}=a^{m-n}$

This can be used to find $\frac{3^{4}}{3^{2}}$ without finding what 3⁴ is. This is how we would do it:

$\frac{3^{4}}{3^{2}}=3^{4-2}=3^{2}=9$

And now we get the solution, 9, which is answer choice B.

I hope you find my answer helpful.
