nomor 1
[tex] ({2m + n})^{4} \\ = {2}^{4} {m}^{4} + {n}^{4} \\ = 16 {m}^{4} + {n}^{4} [/tex]
nomor 2
[tex]( {2x - 3y})^{3} \\ = {2}^{3} {x}^{3} - {3}^{3} {y}^{3} \\ = 8 {x}^{3} - 27 {y}^{3} [/tex]
nomor 3
[tex]( {p + 2q})^{5} \\ = {p}^{5} + {2}^{5} {q}^{5} \\ = {p}^{5} + 32 {q}^{5} [/tex]
nomor 4
[tex]( {5m - 3n})^{2} \\ = {5}^{2} {m}^{2} - {3}^{2} {n}^{2} \\ = 25 {m}^{2} -9 {n}^{2} [/tex]
