(4².2pangkat-4) .(5².3 pangkat negatif 3)²

Penyelesaian:

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

[tex](4^2 . 2^-4) . (5^2 . 3^-3)^2[/tex]
= [tex]((2^2)^2 . 2^-4) . (5^4 . 3^-6)[/tex]
= [tex](2^4 . 2^-4) . (5^4 . 3^-6)[/tex]
= [tex](5^4 . 3^-6)[/tex]
= [tex]( \frac{5^2}{3^3})^2 [/tex]
= [tex] (\frac{25}{27} )^2[/tex]
= [tex] \frac{625}{729} [/tex]
