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:
66 x 66 x 66 x 66 x ... (for a total of 100 times) = 90031306848407769207643021290072028008476321578621294453829726021717783261921522749281789297245411881935635920773218112928431706337816398700648297562534393629326112095021903827173376
Therefore, 66 to the power of 100 is 90031306848407769207643021290072028008476321578621294453829726021717783261921522749281789297245411881935635920773218112928431706337816398700648297562534393629326112095021903827173376.
