Hey buddy!!
Here is your answer!!
===================
(1) 4x²-3x+7
➡️One variable is involved in given polynomial which is 'x'. Therefore, it is a polynomial in one variable 'x'.
(2) y²+√2
➡️One variable is involved in given polynomial which is 'y'. Therefore, it is a polynomial is one variable 'y'.
(3) 3√t+t√2
➡️No, it can be observed that the exponent of variable t in term 3√t is ½, which is no number. There this number is not a polynomial.
(4) y+2/y = y+2y^-1
➡️The power of variable 'y' is -1 which is not a whole number. Therefore it is not a polynomial in one variable.
(5) x^10+y³+t^50
➡️In the given expression, there are three variables 'x', 'y' & 't' involved. Therefore it is not a polynomial in one variable.

HOPE IT HELPS YOU!!
