Write down the expansion of `(a+b)^8` using Pascal's triangle.

Text Solution

Verified by Experts

The row n = 8 in the Pascal's triangle is 1, 8, 28 , 56, 70, 56, 28, 8, 1.
therefore `(a+b)^8` = `a^8+8a^(8-1)b^-1+28a^(8-2)b^2+56a^(8-3b)^3+70a^(8-4)b^5+56a^(8-5)b^5+28a^(8-6)b^6+8a^8-7)+b^8`
= `a^8+8a^7b+28a^6b^2+56a^5b^3+70a^4b^4+56a^3b^5+28a^2b^6+8ab^7+b^8`
