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:
75 x 75 x 75 x 75 x ... (for a total of 89 times) = 75936826223161458975266687085877343708298749962167102816631272113599015765584263611364781668620995979558882388222285768307191593240457194724513101391494274139404296875
Therefore, 75 to the power of 89 is 75936826223161458975266687085877343708298749962167102816631272113599015765584263611364781668620995979558882388222285768307191593240457194724513101391494274139404296875.
