Tolong bantu jawab no. 4 yaaa..terimakasihh

Penyelesaian:

Ingat: a^m . a^n = a^m+n
a^m / a^n = a^m-n
a^m^n = a^mn

[tex] \frac{25 . a . b . c}{5 . a^3 . b^5 . c^4}^-2 [/tex]
= [tex] \frac{5 . a . b . c}{a^3 . b^5 . c^4}^-2 [/tex]
= (5a^-2 . b^-4 . c^-3)^-2
= [tex] \frac{a^4 . b^8 . c^6}{25} [/tex]
