Question

(m+n/3) (m-n/7)..........​

Answer 1

Answer:

${(m + \frac{n}{7}) }^{3} (m - \frac{n}{7} ) \\(m + \frac{n}{7} )(m - \frac{m}{7} ) {(m + \frac{n}{7} )}^{2} \\ ({m}^{2} - \frac{ {n}^{2} }{49} )( {m}^{2} + \frac{ {n}^{2} }{49} + \frac{2mn}{7}) \\ {m}^{4} + \frac{ {m}^{2} {n}^{2} }{49} + \frac{2 {m}^{3}n }{7} - \frac{ {m}^{2} {n}^{2} }{49} - \frac{ {n}^{4} }{2401} - \frac{2m {n}^{3} }{7} \\ {m}^{4} - \frac{ {n}^{4} }{2401} + \frac{2 {m}^{3}n }{7} - \frac{2m {n}^{3} }{7} \\ \\ i \: hope \: its \: is \: helpfull \: for \: u$
