You can put this solution on YOUR website!
log base5(sqrt 125)= x
write the exponent equiv of logs
5%5Ex+=+sqrt%28125%29
Square both sides
5%5E%282x%29+=+125
using common logs
log%28%285%5E%282x%29%29%29+=+log%28%28125%29%29
which is
2x * log(5) = log(125)
2x = log%28125%29%2Flog%285%29
use a calc
2x = 3
x = 1.5
:
:
check this on a calc
enter 5^1.5 = 11.18
enter sqrt%28125%29 = 11.18
