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:
63 x 63 x 63 x 63 x ... (for a total of 70 times) = 899163070614568073616813758753919018435453578365690913337878034110455297410762063088078519993399865451742661467630593242488449
Therefore, 63 to the power of 70 is 899163070614568073616813758753919018435453578365690913337878034110455297410762063088078519993399865451742661467630593242488449.
