Step 1.1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$5 \frac{1}{x^{4}} + x^{2}$

Step 1.2

Combine $5$ and $\frac{1}{x^{4}}$ .

$\frac{5}{x^{4}} + x^{2}$

Step 2

The degree cannot be determined because $\frac{5}{x^{4}} + x^{2}$ is not a polynomial.

Not a polynomial
