(m+4n)^2
identity : (a+b)^2 = a^2+b^2+2ab
so m^2 +(4n )^2 + 2 × m × 4n
= m^2+ 16n^2 +8mn
identity : (a+b)^2 = a^2+b^2+2ab
so m^2 +(4n )^2 + 2 × m × 4n
= m^2+ 16n^2 +8mn

ok u know multiplication of algebric terms
Yes
ok
then u multiply them wait a min I will explain
(m + 4n)sq ( sq is square
ok
then (m+4n)×(m+5n)
sorry (m+ 4n ) ×( m+4n)
Do it in your answer buddy!!!!!
then solve it

See boy,
(a + b)² = ( a + b )(a + b) = a(a + b) + b(a + b) = a² + 2ab + b²
GOT IT...
Soo, now,
a = m , b = 4n
.'. (m + 4n)² = m² + 2(m)(4n) + (4n)² = m² + 8mn + 16n²
There you have it...... Hope you understand it well!!!!!!
