simplify:

x^(3/2)(x + x^(5/2) - x^2)

add exponents when multiplying. For instance, the first term above

x^3/2 * x=x^3/2 * x^2/2=x^5/2

add exponents when multiplying. For instance, the first term above

x^3/2 * x=x^3/2 * x^2/2=x^5/2

ok, so would the answer be x^3

no. I will be happy to critique your work.

no. I will be happy to critique your work.

x^(3/2)(x + x^(5/2) - x^2)
x^(5/2) + (x^4 - x^(7/2))
x^3
