WebOct 15, 2014 · Binary Exponentiation is based on the idea that, to find base ^ power, all we need to do is find base ^ ( power /2) and square it. And this method can be repeated in finding base ^ ( power /2) also. Suppose that we need to find 5^8. 5^8=5^4 * 5^4 5^4=5^2 * 5^2 5^2=5 * 5 The number of steps required to find 5^8 has been reduced from 8 to just 3.
