Hasil dari (4m+3n) pangkat 2 adalah.... pakai cara
fie140114
Cara 1 (4m+3n)² = (4m)²+2.4m.3n+(3n)² = 16m²+24mn+9n² atau bisa ditulis = 16m²+9n²+24mn cara2 (4m+3n)² = (4m+3n) (4m+3n) = (4m.4m)+(4m.3n)+(3n.4m)+(3n.3n) =16m²+12mn+12mn+9n² =16m²+24mn+9n² atau bisa ditulis = 16m²+9n²+24mn
(4m+3n)²
= (4m)²+2.4m.3n+(3n)²
= 16m²+24mn+9n²
atau bisa ditulis
= 16m²+9n²+24mn
cara2
(4m+3n)²
= (4m+3n) (4m+3n)
= (4m.4m)+(4m.3n)+(3n.4m)+(3n.3n)
=16m²+12mn+12mn+9n²
=16m²+24mn+9n²
atau bisa ditulis
= 16m²+9n²+24mn
