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:
68 x 68 x 68 x 68 x ... (for a total of 47 times) = 134251422841156195290249088845912772113076113202258736862487976561268803933048963858432
Therefore, 68 to the power of 47 is 134251422841156195290249088845912772113076113202258736862487976561268803933048963858432.
