Exponents Calculator

This calculator will solve for the exponent n in the exponential equation xn = y, stated x raised to the nth power equals y. Enter x and y and this calculator will solve for the exponent n using log(). Since taking the log() of negative numbers causes calculation errors they are not allowed. How to solve for exponents For xn = y; solve for n by taking the log of both sides of the equation: For: x n = y Take the log of both sides: log ⁡ x n = log ⁡ y By identity we get: n ⋅ log ⁡ x = log ⁡ y Dividing both sides by log x: n = log ⁡ y log ⁡ x
