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:
67 x 67 x 67 x 67 x ... (for a total of 84 times) = 2456311417129543226673784458110020730197693679727633905049170133738306532693346991699068358774485342506824881020892359678741461382407304151927334983237521
Therefore, 67 to the power of 84 is 2456311417129543226673784458110020730197693679727633905049170133738306532693346991699068358774485342506824881020892359678741461382407304151927334983237521.
