$(iii)$ $x^{6}$ નો સહગુણક

$(iv)$ અચળ પદ મેળવો.

$(i)$ We know that highest power of variable in a polynomial is the degree of the polynomial.

In the given polynomial, the term with highest of $x$ is $-x^{6},$ and the exponent of $x$ in this term in $6$

$(ii)$ The coefficient of $x^{3}$ is $\frac{1}{5}.$

$(iii)$ The coefficient of $x^{6}$ is $-1.$

$(iv)$ The constant term is $\frac{1}{5}.$
