5832x^19z^-8
I got all the indices, but got 648 as my coefficient, sure it is 5832?

Also, do you have an answer for the second question you posted? I have an answer, but it doesn't look right

I'll try the question again later, but the only numbers in the question are 9^4, 3^12 and 8 (16^(3/4)), am I missing any here?

Yeah, I thought I had messed up question 2. The only parts I've got matching with your answer is 30 root 10. I'll have to try that one again later too.
