X=3you can put it in a graphic calculator if you have onethe 4 is to the power of x.So 4^3=64Same as doing 4x4x4are you sure it's 63?

You need to use logarithms to solve that one.Take the log of each side:log 4^x = log 63log 4^x can also be written x log 4x log 4 = log 63divide each side by log 4 and you getx = (log 63)/(log 4)put that in your calculator and thats your answer
