The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. y = logax only under the following conditions: x = ay, a > 0, and a≠1.
Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay.
Hence we Solving Exponential and Logarithmic Functions as they inverse.
