Because no one should have to say, "I was never any good at math."
2x^4 means two times four to the fourth power
or 2 times x times x times x times x.
The exponent only applies to the x.
(2x)^4 means that you will distribute the exponent to both the 2 and the x
or 2 times 2 times 2 times 2 times x times x times x times x.
The simplified answer is 16x^4
The exponent is applied to the 2 and the x.
