# Which of the following expressions are polynomials in one variable and which are not? State reasons for your answer:$x^{12}+y^{3}+t^{50}$

Given:

The given expression is $x^{12}+y^{3}+t^{50}$.

To do:

We have to find whether the given expression is a polynomial in one variable.

Solution:

Polynomials:

Polynomials are expressions in which each term is a constant multiplied by a variable raised to a whole number power.

Here, there are three variables ($x, y, t$) in the given expression.

Therefore, $x^{12}+y^{3}+t^{50}$ is not a polynomial in one variable.
