Step-by-step explanation: Exponential form contains a base and an exponent. The base is the number that is multiplied so in this case, 2 is the base. Next we write the exponent which is the number of times that the base is multiplied. Since 2 is multiplied 4 times, the exponent is 4.
So in exponential form, 2 x 2 x 2 x 2 can be written as .
