Q

# Is the following expression polynomial in one variable? State reasons for your answer. (v) x^10 + y ^3 + t ^ 50

1.(v) Is the following expression polynomial in one variable? State reasons for your answer.

(v)    $x^{10} + y^3 + t^{50}$

Because in the given polynomial $x^{10} + y^3 + t^{50}$  there are 3 variables which are x, y, t. That's why this is polynomial in three variable not in one variable
