Question

I need help please!

simplify:
Select one:
a. none of these
b. x20
c. x120
d. x14

Answer 1

Well, first, you must simplify each monomial and get rid of the parentheses. This can be done by adding the exponents together, as
`x^3` is being multiplied by
`4`. The same goes for
`x^2`. This would give you the expression:
`x^7*x^7`

Once again, add the two exponents together and you get your answer:
`x^1^4`

Answer 2

It would be (x^7)*(x^7)
