Bentuk sederhana dari 15p*5q-³ : 3p²q .(q²)³ adalah....
a. 3p³q²
b. 5p³q²
c. 5p³q²
d. 5p*7q²
e. 5p*7q*5​

(B). [tex]{5p}^{3} {q}^{2}[/tex]

PEMBAHASAN :

[tex]{15p}^{5} {q}^{ - 3} \div {3p}^{2} q \times {({q}^{2})}^{3} [/tex]

[tex]= (15 \div 3) {p}^{5 - 2} {q}^{( - 3) - 1} \times {q}^{2 \times 3} [/tex]

[tex]= {5p}^{3} {q}^{ - 4} \times {q}^{6} [/tex]

[tex]= {5p}^{3} {q}^{( - 4) + 6} = {5p}^{3} {q}^{2}[/tex]
