Question from Maths exemplar class 9 chapter Polynomials
Answers
Answer:
c) is the answer
Step-by-step explanation:
a) It is not a polynomial, because one of the exponents of x is – 2, which is not a whole number.
b) It is not a polynomial, because exponent of x is 1/2 which is not a whole number.
c) It is a polynomial, because each exponent of x is a whole number.
d) It is not a polynomial because it is a rational function.
pls mrk as brainliest plsssss :) thx :)
Answer:
there is no polynomial in the given expressions
Step-by-step explanation:
An algebraic expression having the non negative integral powers of its variables
But a)the variable x has a rational number in its power so it is not a polynomial
b)the variable x is under root that is it has a rational number as it's power so it is not a polynomial
c) the variable x is in underroot so it's not a polynomial
d) the variable x is in denominator so it has a negative power so it's not a polynomial
