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 79 times) = 668925340282152130459451743207061282914065722128262870058466950677948211930325312738035259506927835068201786769896292321769794333286085397652486871842816
Therefore, 86 to the power of 79 is 668925340282152130459451743207061282914065722128262870058466950677948211930325312738035259506927835068201786769896292321769794333286085397652486871842816.
