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:
74 x 74 x 74 x 74 x ... (for a total of 91 times) = 125917616849384704891114678967008781857590360625625737329101324633083603794749575077604012328903351571690116484277485137782608736700059737704216268693456792458196181581824
Therefore, 74 to the power of 91 is 125917616849384704891114678967008781857590360625625737329101324633083603794749575077604012328903351571690116484277485137782608736700059737704216268693456792458196181581824.
