Question

3x^3 + 2x^1/2 + x + 5 is

a) a polynomial

b) an algebraic expression

c) None of these​

Answer 1

Polynomial : An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

Algebraic expression : In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).[1] For example, 3x2 − 2xy + c is an algebraic expression. Since taking the square root is the same as raising to the power 1/2, is also an algebraic expression.

Therefore it is an algebraic expression .
