Math Tutor's Solution: 81 to the Power of 20 is equal to 147808829414345923316083210206383297601
Methods
Step-by-step from math tutor: finding 81 to the power of 20
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 . To solve this, we need to multiply the base, 2 by itself, 4 times - = 16. So .
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:
81 x 81 x 81 x 81 x ... (for a total of 20 times) = 147808829414345923316083210206383297601
Therefore, 81 to the power of 20 is 147808829414345923316083210206383297601.
