 Question 475131: solve for x: (9a^2b)^x(3ab)^4=9^5a^10b^7 I am not sure how to solve for x or even how to isolate it when it is an exponent. Especially when there are so many other variables(a, b) and a huge number (9 raised to the 5th power=59,049). There is just too much going on with this one for me to solve on my own.
