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.
