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:
67 x 67 x 67 x 67 x ... (for a total of 89 times) = 3316327714877346181774068495600728756130379310495495456911338667074635417451404105355832779690716411921958590718594566346743301174259029435702437400468401246539747
Therefore, 67 to the power of 89 is 3316327714877346181774068495600728756130379310495495456911338667074635417451404105355832779690716411921958590718594566346743301174259029435702437400468401246539747.
