How many solutions can you find to the equation: x^y=y^x (x does not equal y) The answer is: one, 2^4 = 4^2 I couldn't figure this one out. After looking at the solution, the only way I can think of is through trial and error, even though it might take a long time to get the right answer. Is there another way to get the answer? Thanks.

Some more info on it here. Check the links in the top answer. EDIT: To answer your question, there are other ways (see links), but I'm not sure whether those methods are taught at year 10 level. Last edited by skipjack; February 23rd, 2017 at 12:02 PM.
