The first step a math tutor would suggest is to understand what it means when a number has an exponent. The “power” of a number indicates how many times the base would be multiplied by itself to reach the correct value.
The second step is to write the number in the base-exponent form, and lastly calculate what the final result would be. Consider the example of 2 to the power of 4: in exponent form that would be
So re-applying these steps to our particular problem, we first convert our word problem to a base-exponent form of:
To simplify this, all that is needed is to multiply it out:
89 x 89 x 89 x 89 x ... (for a total of 53 times) = 20781187085996015824298712957168382459991660329528900373023380160788693718056328191139455672283294646969
Therefore, 89 to the power of 53 is 20781187085996015824298712957168382459991660329528900373023380160788693718056328191139455672283294646969.
