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:
36 x 36 x 36 x 36 x ... (for a total of 90 times) = 116741446195279078628053382791335881633270131715832481723779676398836856930282974584939114053628368372944886748404030500135265750611474251776
Therefore, 36 to the power of 90 is 116741446195279078628053382791335881633270131715832481723779676398836856930282974584939114053628368372944886748404030500135265750611474251776.
