Since sum of all binomial coefficients is 2n
5C0 + 5C1 + 5C2 + 5C3 + 5C4 + 5C5 + (5C1 + 5C2 + 5C3 + 5C4)
= 25 + (25 - (5C0 + 5C5)
= 32 + 32 - (1 + 1)
= 64 - 2 = 26 - 2

\(6-2 r =0 = r =3 \)
\(t_{r+1} =6 C_3 2^3=160 \)
9.
\(\text { M.T } =t_{\frac{n}{2}}+1=t_{5+1}=t_6 \quad r=5 \)
\(t_6 =10 C_5\left(x^5\right)\left(\frac{1}{x^5}\right)=10 C_5 \)
