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:
93 x 93 x 93 x 93 x ... (for a total of 90 times) = 1457019519026308231814458738782964311503655899196264482105974514250652013672606320864286997004263923082061780895858939634021641016738767055184440533839003886725691906373673614249
Therefore, 93 to the power of 90 is 1457019519026308231814458738782964311503655899196264482105974514250652013672606320864286997004263923082061780895858939634021641016738767055184440533839003886725691906373673614249.
