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:
86 x 86 x 86 x 86 x ... (for a total of 75 times) = 12228800028909114088160069553753298358731352785089401044007587577449451794838404471663370789695858194660236636504586921002600661995354610389221376
Therefore, 86 to the power of 75 is 12228800028909114088160069553753298358731352785089401044007587577449451794838404471663370789695858194660236636504586921002600661995354610389221376.
