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:
66 x 66 x 66 x 66 x ... (for a total of 68 times) = 5357813804199494224857098285717492888964544959174553592759205850055068794649049030355355307956097042367948602804538332676096
Therefore, 66 to the power of 68 is 5357813804199494224857098285717492888964544959174553592759205850055068794649049030355355307956097042367948602804538332676096.
