Question

Factor the expression by removing the common factor with the lesser exponent. (Factor your answer completely.)

Answer 1

3x^7+x^-4

Answer 2

\[3 x^7+\frac{1}{x^4} \]cannot be factored from my experience.

Answer 3

I t says to factor out the -4

Answer 4

\[3x^7+x^{-4}=x^{-4}(3x^{11}+1)\]
This is really unnecessary though
