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 98 times) = 216458102203766369467173793595429257163905485250760319158213065139688157164948571955450109001288650328202936782978581658219730667301913796529289566505762765036884939841974368129
Therefore, 63 to the power of 98 is 216458102203766369467173793595429257163905485250760319158213065139688157164948571955450109001288650328202936782978581658219730667301913796529289566505762765036884939841974368129.
