mohon di bantu ya terima kasih banyak

NOMOR 9 :
[tex](5a {}^{3} ) {}^{5} \div ( - 5 {}^{4} a {}^{3} ) {}^{5} \\ = 5 {}^{5} a {}^{15} \div - 5 {}^{20} a {}^{15} \\ = - 5 {}^{ - 15} [/tex]

NOMOR 10 :
[tex](4/3 a){}^{2} \div (a {}^{3}b{}^{5}){}^{6}\\ = 4/3{}^{2}a{}^{2} \div a{}^{18}b{}^{30}\\ = 16/9\: a{}^{2} \div a{}^{18}b{}^{30}\\ = 16/9\: a{}^{-18} \div b{}^{30}[/tex]

saya kurang yakin nomor 10 jadi maaf kalo salah

SEMOGA MEMBANTU :)
