Write in exponent form: 2x⋅2x⋅2x⋅2x (1 point)

2^4x

answer choices

Because we only worry about the exponent of the variable, 2⋅x^4
Because these are like terms, we just add the coefficients to get 8x
Because when you are multiplying with exponents, you would add to get 8⋅x^4
Because there are 4 factors of 2 and 4 factors of x, 2^4⋅x^4

Because there are 4 factors of 2 and 4 factors of x, 2^4⋅x^4
