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:
77 x 77 x 77 x 77 x ... (for a total of 86 times) = 1730622576154641609178929792306132600835862553349964628093190133848443065455636649367831507208455772828940881320921207407339763218281020655529745687875066350887289
Therefore, 77 to the power of 86 is 1730622576154641609178929792306132600835862553349964628093190133848443065455636649367831507208455772828940881320921207407339763218281020655529745687875066350887289.
