Answer:
Fourth degree polynomial
Given is an algebraic expression with 4 terms as
5x+3x^4-7x^3+105x+3x
4
−7x
3
+10
First let us arrange these terms in the descending powers of x.
We get
3x^4-7x^3+5x+103x
4
−7x
3
+5x+10
is the standard way of representing any polynomial.
This is a polynomial because x has powers only as non negative integers.
The degree is 4 since the leading term or highest degree term has degree 4.
This is a polynomial as this got more than 3 terms after simplification.
Hence Option B is the answer.
