Verified Solution

Answer & Solution

Correct Answer

(B) \(32\)

Step-by-step Solution

Detailed explanation

\(\alpha( m , n )=\int \limits_0^2 t ^{ m }(1+3 t )^{ n } dt\) \(\text { If } 11 \alpha(10,6)+18 \alpha(11,5)= p (14)^6 \text { then } P\) \(=11 \int \limits_0^2 \frac{ t ^{10}}{ II } \frac{(1+3 t )^6}{ I }+10 \int^2 t ^{11}(1+3 t )^5 dt\)…
