The first step 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 77 times) = 90444205013811807796031874419559394661177085198521210121480117722816145474624839472422290360590567207707110163587924867735234496117642698438681296896
Therefore, 86 to the power of 77 is 90444205013811807796031874419559394661177085198521210121480117722816145474624839472422290360590567207707110163587924867735234496117642698438681296896.
