Hi Sarah,

Since both your variable (x) and your exponent (3) are the same for all four terms (aka like terms), you can add them together.

X³ has an invisible coefficient of 1, so you will be adding 1x³+1x³+1x³+1x³.

When adding like terms, the variable and the exponent stay the same. What changes are the coefficients, which are added together following normal rules for addition, so 1x³+1x³+1x³+1x³ = (1+1+1+1)x³ = 4x³

Your final answer is 4x³.
