Free interactive math game: Exponential Equation — 2^x = 32. Part of the Logarithms category on MathKite.
Taken from the generator that powers this exercise. A fresh set appears every time the page is opened, and the printable worksheet holds ten of them.
Equations where the unknown sits in the exponent.
Write both sides as powers of the same base, then the exponents themselves must be equal.
From 2 to the power x equals 32, and 32 is 2 to the power 5, so x = 5.
Dividing both sides by the base. That changes the equation without isolating the exponent.
