Jawab: ..............................?
SOAL A.
[tex] {3}^{3} \times {3}^{3} = {3}^{3 + 3} = {3}^{6} [/tex]
SOAL B.
[tex] {( - 2)}^{3} \times {( - 2)}^{2} = {( - 2)}^{3 + 2} = {( - 2)}^{5} [/tex]
SOAL C.
[tex] {z}^{3} \times {2z}^{7} \times {(3z)}^{2} [/tex]
[tex] ={z}^{3} \times {2z}^{7} \times {3}^{2} {z}^{2} [/tex]
[tex] = (2 \times {3}^{2}) {z}^{3 + 7 + 2} [/tex]
[tex] = (2 \times 9) {z}^{3 + 7 + 2} [/tex]
[tex] = {18z}^{12} [/tex]
SOAL D.
[tex]( {3x}^{3}) \times {(xy)}^{4} [/tex]
[tex] = ( {3x}^{3} ) \times ( {x}^{4} {y}^{4})[/tex]
[tex] = {3x}^{3 + 4} {y}^{4} [/tex]
[tex] = {3x}^{7} {y}^{4} [/tex]
