Question 277511: The question is:
simplify 4 + x^-1
________
64+ x^-3
I factored the terms and made the exponents positive.
4+x^1
______
(4+x)(4-x)(4-x)
x^3 minus x = x^2 which is the numerator of the answer.
(4+x) is cross cancelled leaving the denominator of the answer to be 16.
I think the answer is
X^2
___
16
Any help is welcome. Thank you.
