Monomial
Difference of two squares
Radical expression
Sum of two squares
Polynomial
Complex conjugate

Answer 1

Monomial: A statement with one "thing". This has two things, so, no.

Difference of Two Squares: This is addition, not difference.

Radical Expression: Radicals are roots like \(\sqrt{2}\), so no.

Sum of Squares: \(x^4 = (x^2)^2\) and \(400 = 20^2\), so yes.

Polynomial: A sum of constant multiplied powers of a variable. \(x^4 + 400 = x^4 + 400x^0\), so yes.

Complex Conjugate: No.

Answer 2

Thank you! :) So, Sum of Squares and Polynomial?

Answer 3

Yep!
