( 5a3 ) : ( 25a3 )5=

(5a³) : (25a³)^5
5a³ : 25a^15
=5a pangkat 12

maap kalo salah

[tex]= \frac{5a^3}{(25a^3)^5} \\ \\ = \frac{5a^3}{(5^2a^3)^5} \\ \\ = \frac{5a^3}{5^{(2 \times 5)}a^{(3 \times 5)}} \\ \\= \frac{5a^3}{5^{10}a^{15}} \\ \\ =5^{(1-10)}.a^{(3-15)} \\ \\ =5^{(-9)}.a^{(-12)} \\ \\ =(5^{3}a^{4})^{-3} \\ \\ = \frac{1}{(125a^4)^3} [/tex]
