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:
29 x 29 x 29 x 29 x ... (for a total of 90 times) = 412876163830129141719696825306774096522784009170266548972077860557379337563903603905788436282113262572856055665137152460350893141801
Therefore, 29 to the power of 90 is 412876163830129141719696825306774096522784009170266548972077860557379337563903603905788436282113262572856055665137152460350893141801.
