Solution 1
(i)
Yes, this expression is a polynomial in one variable x.
(ii)
Yes, this expression is a polynomial in one variable y.
(iii)
No, here the exponent of variable t in term which is not a whole number.
So this expression is not a polynomial.
(iv)
No, here the exponent of variable t in term is -1, which is not a whole number. So this expression is not a polynomial.
(v)
No, this expression is a polynomial in 3 variables x, y and t.
Concept Insight: In such problems to check whether the given algebraic expressions is a polynomial or not, check the exponents of variable to be a whole number. The second step is to look for the number of variables the expression has. Any alphabet used in the expression is the variable unless specified as constant.
