Find each value of x.
log4 x = 1/2
the 4 next to the log in like an exponent but shows below it. Thanks! This question is from textbook college algebra

Solve:
log%284%29%28x%29+=+1%2F2 The 4 here is the base of the logarithm.
You can rewrite this equation in exponental form according to the following:
log%28b%29%28x%29+=+y means b%5Ey+=+x Applying this to your equation:
log%284%29%28x%29+=+1%2F2 means:
4%5E%281%2F2%29+=+x or
sqrt%284%29+=+x
x = +/- 2
