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:
65 x 65 x 65 x 65 x ... (for a total of 91 times) = 944311882389152441883985640549737021006087957197293243785279629093326576567514991986210162980820366594493350534112098248183155002610789097161614336073398590087890625
Therefore, 65 to the power of 91 is 944311882389152441883985640549737021006087957197293243785279629093326576567514991986210162980820366594493350534112098248183155002610789097161614336073398590087890625.
