Question

(m³-n²m)² explain with identities pls note identities​

Answer 1

Answer:

$( {m}^{3} - {n}^{2} m) ^{2} \\ \\ formula \: to \: be \: used \\ \\ (a - b) ^{2} \\ \\ = {a}^{2} - 2ab + {b}^{2} \\ \\ here \: a = {m}^{3} \\ \\ and \: b = {n}^{2} m \\ \\ using \: it \: we \: get \\ \\ ( {m ^{3}) }^{2} - 2 \times {m}^{3} \times {n}^{2} m + ( {n}^{2} m)^{2} \\ \\ = {m}^{6} - 2 {m}^{4} {n}^{2} + {n}^{4} {m}^{2} \\ \\ =\:m^2 (m^4 - 2m^2n^2 + n^2) \\ \\ = m^4 - 2m^2n^2 + n^2$
