Question

Guys help me I really need your help​

Answer 1

a x^2/2 is a polynomial because the power of x is 2 which is a positive whole number but 2/x^2 is not a polynomial because the power of x is -2 which is negative whole number.

b.in

`√(2 x)`

the power if x will be

`x {}^{ (1)/(2) }`

which is not a whole number so it is not a polynomial.

but in

`√(2) x`

the power if x is a positive whole number.so it is a polynomial.

c.the greatest power of variable of the term is called degree of polynomial
