Solution: 3 to the Power of 81 is equal to 4.434264882430377e+38
Methods
Step-by-step: finding 3 to the power of 81
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
2
4
2^4
2 4
. To solve this, we need to multiply the base, 2 by itself, 4 times -
2
⋅
2
⋅
2
⋅
2
2\cdot2\cdot2\cdot2
2 ⋅ 2 ⋅ 2 ⋅ 2
= 16. So
2
4
=
16
2^4 = 16
2 4 = 16
.
So re-applying these steps to our particular problem, we first convert our word problem to a base-exponent form of:
3
81
3^{81}
3 81
To simplify this, all that is needed is to multiply it out:
3 x 3 x 3 x 3 x ... (for a total of 81 times) = 4.434264882430377e+38
Therefore, 3 to the power of 81 is 4.434264882430377e+38.
