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:
58 x 58 x 58 x 58 x ... (for a total of 91 times) = 29644724199368295988102054920540149823935264079524834914975939799231072844082693862654826796410056461247155042745631360826517540518719391939067512243559273070592
Therefore, 58 to the power of 91 is 29644724199368295988102054920540149823935264079524834914975939799231072844082693862654826796410056461247155042745631360826517540518719391939067512243559273070592.
