The first step a math tutor would suggest 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 89 times) = 12396332907883529511573276158587130525773249733669681878437017501427561697850245574700224154040070412643171826900040953451826135428650813468041800015136008666349568
Therefore, 68 to the power of 89 is 12396332907883529511573276158587130525773249733669681878437017501427561697850245574700224154040070412643171826900040953451826135428650813468041800015136008666349568.
