Write in exponent form: 2x * 2x * 2x * 2x (1 point)
Because there are 4 factors of 2 and 4 factors of x, 2^(4) * 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 we only worry about the exponent on the variable, 2 * x^(4)
