Question

1) find the middle term in the expansion of (7p+2q) ^8.​ do the problem i will give you brain list mark please​

Answer 1

Answer:

Given expansion is (7p+2q)⁸.

Here, n=8 (even)

So, Middle term=Tn/2+1=T4+1

=⁸C4(7p)⁴(2q)⁴

=⁸C4(7)⁴p⁴(2⁴)q⁴

Middle term=(⁸C4.7⁴.2⁴)p⁴q⁴

Step-by-step explanation:

Hope it helps you frnd....
