Logarithmic to Exponential Form

Logarithmic functions are inverses of exponential functions .  So, a log is an exponent !

y = log b x if and only if b y = x for all x > 0 and 0 < b ≠ 1 .

Example 1:

Write log 5 125 = 3 in exponential form.

      5 3 = 125

Example 2:

Write log z w = t in exponential form.


    z t = w
