Question

In each pair of expressions below, encircle the expression that is not a polynomial then write the reason why on the space provided for.

Answer 1

Step-by-step explanation:

Polynomial: it is of expression in which the exponent of all variable should be whole number.

According to this , the expression which are not polynomial are,

`\begin{gathered} 1)(4)/(x)-5\ldots\ldots\ldots\text{.}\mathrm{}\text{ exponent for x is -1} \\ 2)x^(-5)-4x^3+x\ldots\ldots\text{... exponent for x is -}5 \\ 3)4\sqrt[]{x}\ldots\ldots\ldots\ldots\text{.. exponent for x is fraction that is }(1)/(2) \\ 5)(x+3)(2x-3)^(-2)\ldots\text{. exponent for x is -}2 \end{gathered}`

All the above expressions are not polynomial.
