Answer: 3⁴
Explanation: Exponential form contains a base and an exponent.
The base is the number that is multiplied.
So in this case, 3 is the base.
Next we write the exponent which is the
number of times that the base is multiplied.
Since 3 is multiplied four times, the exponent is 4.
So in exponential form, 3 · 3 · 3 · 3 can be written as 3⁴.
