1. (a³/b⁴)⁵=

2. (x y⁵ z²)⁹=

3. (x⁴ y⁵/z⁷)¹²=

​

Dengan memakai sifat (a/b)n =an/bn

Penjelasan dengan langkah-langkah:

Nomor 1

= {( frac{ {a}^{3} }{ {b}^{4} } )}^{5}

= frac{ {a}^{3 times 5} }{ {b}^{4 times 5} }

= frac{ {a}^{15} }{ {b}^{20} }

:

Nomor 2

= {(x {y}^{5} {z}^{2} )}^{9}

= {x}^{1 times 9} {y}^{5 times 9} {z}^{2 times 9}

= {x}^{9} {y}^{45} {z}^{18}

:

Nomor 3

= {( frac{ {x}^{4} {y}^{5} }{ {z}^{7} } )}^{12}

= frac{ {x}^{4 times 12} {y}^{5 times 12} }{ {z}^{7 times 12} }

= frac{ {x}^{48} {y}^{60} }{ {z}^{84} }
