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:
52 x 52 x 52 x 52 x ... (for a total of 90 times) = 27561377981918986342604692603410541509580462862804919929657734808969227350118603317039344514617861442416745730328960008590421788967921072750363627931828224
Therefore, 52 to the power of 90 is 27561377981918986342604692603410541509580462862804919929657734808969227350118603317039344514617861442416745730328960008590421788967921072750363627931828224.
