Evaluate the following:
a)log%285%2C%28125%29%29 = y
The exponent equiv of logs
5%5Ey+=+125 (125 is 5 cubed)
y = 3
:
b)log%287%2C%28sqrt%287%29%29%29 = y
7%5Ey+=+sqrt%28%287%29%29
exponent equiv of radical
7%5Ey+=+7%5E%281%2F2%29
y = 1%2F2
:
c)log%28%280.001%29%29 = y
10%5Ey=.001
10%5Ey+=+10%5E-3
y = -3
