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:
39 x 39 x 39 x 39 x ... (for a total of 89 times) = 4024853019776635641939579528950380113414655429664562316865365752176542516012813603253026008592281377584769758699426216024473274856484072073959
Therefore, 39 to the power of 89 is 4024853019776635641939579528950380113414655429664562316865365752176542516012813603253026008592281377584769758699426216024473274856484072073959.
