Text Solution

Verified by Experts

`(2x+7)^(5)=.^(5)C_(0)(2x)^(5)+.^(5)C_(1)(2x)^(4)(7)^(1)+.^(5)C_(2)(2x)^(3)(7)^(2)+.^(5)C_(3)(2x)^(2)(7)^(3)+.^(5)C_(4)(2x)(7)^(4)+.^(5)C_(5)(7)^(5)`
`=32x^(5)+56x^(4)+3920x^(3)+13720x^(2)+24010x+16807`
thus, `(2x+7)^(5)=32x^(5)+560x^(4)+3920x^(3)+13720x^(2)+24010x+16807`
