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:
98 x 98 x 98 x 98 x ... (for a total of 91 times) = 15906436205108635557254961498566075659751178946252103278602654014485907302823182004436614756613505423015447401670969777852350611241301999896909377378018117935945630121294195905789952
Therefore, 98 to the power of 91 is 15906436205108635557254961498566075659751178946252103278602654014485907302823182004436614756613505423015447401670969777852350611241301999896909377378018117935945630121294195905789952.
