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:
47 x 47 x 47 x 47 x ... (for a total of 90 times) = 3081819609348702575993710664086973378213775077494296491025662508716527867059742510518129558368670228609205866092648641076825215755720847840202232380449
Therefore, 47 to the power of 90 is 3081819609348702575993710664086973378213775077494296491025662508716527867059742510518129558368670228609205866092648641076825215755720847840202232380449.
