Your starting equation is in an unhelpful form. Try to clean it up by getting rid of awkward operators such as logarithms.
Remember that \(k^{log_k x} = x\). And if x=y, then \(k^x = k^y\). You can use exponentiation to remove pesty logarithms from equations.
Remember that a fractional power e.g. 1/n is the same thing as taking an nth root? How would you manipulate both sides of an equation to remove an annoying square root? Ok, how about removing an annoying nth root?
