Question

State True or False.
The following expression is a polynomial:

$\sqrt{y}+5y-1$

• A. True
• B. False

Answer 1

The correct option is B False

Expression $\sqrt{y}+5y-1$ can be written as $y^{\frac{1}{2}}+5y-1$.
Clearly, it is not a polynomial as power of y is $\frac{1}{2}$, which is not a whole number.
Therefore, given expression is not a polynomial.
