Introduction

In mathematics, a polynomial is an expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication. The coefficients can be numbers or algebraic expressions, and the variables can be any letters or symbols. In this article, we will analyze the given expression $$p^5 + 9p^3\sqrt{7} + 10p^4$$ to determine if it is a polynomial or not. If it is a polynomial, we will state the type and degree of the polynomial.

What is a Polynomial?

A polynomial is a mathematical expression that consists of variables and coefficients combined using only addition, subtraction, and multiplication. The coefficients can be numbers or algebraic expressions, and the variables can be any letters or symbols. For example, $$2x^2 + 3x - 4$$ is a polynomial, where $$x$$ is the variable and $$2, 3,$$ and $$-4$$ are the coefficients.

Types of Polynomials

Polynomials can be classified into different types based on the number of terms they have. The main types of polynomials are:

Monomial: A monomial is a polynomial with only one term. For example, $$3x^2$$ is a monomial.
Binomial: A binomial is a polynomial with two terms. For example, $$2x^2 + 3x$$ is a binomial.
Trinomial: A trinomial is a polynomial with three terms. For example, $$2x^2 + 3x - 4$$ is a trinomial.

Degree of a Polynomial

The degree of a polynomial is the highest power of the variable in the polynomial. For example, in the polynomial $$2x^2 + 3x - 4$$, the highest power of $$x$$ is $$2$$, so the degree of the polynomial is $$2$$.

Analysis of the Given Expression

Now, let's analyze the given expression $$p^5 + 9p^3\sqrt{7} + 10p^4$$. To determine if it is a polynomial, we need to check if it meets the definition of a polynomial.

The expression consists of variables and coefficients combined using only addition and multiplication.
The coefficients are numbers or algebraic expressions.
The variables are any letters or symbols.

Therefore, the given expression meets the definition of a polynomial.

Type of the Polynomial

To determine the type of the polynomial, we need to count the number of terms in the expression.

The expression has three terms: $$p^5$$, $$9p^3\sqrt{7}$$, and $$10p^4$$.
Therefore, the expression is a trinomial.

Degree of the Polynomial

To determine the degree of the polynomial, we need to find the highest power of the variable in the expression.

The highest power of $$p$$ in the expression is $$5$$.
Therefore, the degree of the polynomial is $$5$$.

Conclusion

In conclusion, the given expression $$p^5 + 9p^3\sqrt{7} + 10p^4$$ is a polynomial. It is a trinomial of degree $$5$$.

Answer

The correct answer is:

C. Trinomial
