Find x when 2^x=16^y, 16^x=8^(y1)
Okay when I exponentiate for the first part I get y=x/3 and for the second part I get y=4x1/3. However, I don't understand how to get one x. I don't know what the next step is. Please help me.

Best ResponseYou've already chosen the best response.0okay I see how you got that but in order to find x do I have to set them equal to each other? I am given answers and it is not in that form. The answers are like in fraction form.

Best ResponseYou've already chosen the best response.0I have a question @khuangg , howcome on 16^x=8^(y1) you distributed the exponent 3 in to (y1) but on the other side you didn't distribute the 4 in to the x?
