Please can someone help with this problem: solve Now we were told to let y=2 but I can't figure out where the y is coming from? Is it just as a function of x?

Thanks in advance for your help!

## Re: Log question

You might have misread your book and it is telling you to make the substitution y=2

^{x}

If not, do that substitution anyway and solve for y, after you have solved for y then finish by using it to find x

Hint: 2^{2x+1}=2(2^{x})^{2 }Edit: Beat plato by 1 minute :P
