Hi

The name is Chris, I am the father of a boy in year 11. My maths classes were many years ago and I only ever got to year 10

Can you help me help him?

he has the following problem

9^{x+1}/3^{2x-1}find to the power of 3

Now I know the answer is 3^{3}but I need to understand the steps to get to it

That way I can work through it with him

I know it must be simple as wolframalpha doesnt even bother showing the steps

Thanks in advance
