Just remember that whenever (probably not always) you get a problem like this the top number will be the first divide thing and the bottom is the second divide.
Hope this helps and sorry for saying the exact term, I am in a rush :)
When your multiplying exponents in the same parenthasis like x^2*x^4, you'll add the exponents so it will be x^6. If it is outside the parenthasis like (x^2)^4 you'll multiply the exponents so it will be x^8. good luck! :)
