Which expressions are polynomials? Select EACH correct answer.

A: 3y2(x^1/4)

B: 9x2(y^5)

C:  4x2(y^5)

D: 8x2(3^y)

Solution:

According to this question option B and C are correct.

A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. a variable's exponents can only be 0,1,2,3,... etc. A polynomial can not have any exponent as a variable or a fraction
