lengkap dengan jalannya ya kak, senin kmpl, makasih
Jawab:
Nomor 1:
[tex]( - 4) {}^{ - 2} {x}^{3} {y}^{ - 2} \\ = \frac{1}{ {( - 4)}^{2} } {x}^{3} \frac{1}{ {y}^{2} } \\ = \frac{1}{( - 4) \times ( - 4)} {x}^{3} \frac{1}{ {y}^{2} } \\ = \frac{1}{16} {x}^{3} \frac{1}{ {y}^{2} } \\ = \frac{ {x}^{3} }{16} \times \frac{1}{ {y}^{2} } \\ = \frac{ {x}^{3} }{16 {y}^{2} } [/tex]
Nomor 2:
[tex] {2}^{5} {a}^{ - 3} {b}^{5} {c}^{ - 2} \\ = {2}^{5} \times \frac{1}{ {a}^{3} } {b}^{5} \frac{1}{ {c}^{2} } \\ = (2 \times 2 \times 2 \times 2 \times 2) \times \frac{ {b}^{5} }{ {a}^{3} } \times \frac{1}{ {c}^{2} } \\ = 32 \times \frac{ {b}^{5} }{ {a}^{3} {c}^{2} } \\ = \frac{32 {b}^{5} }{ {a}^{3} {c}^{2} } [/tex]
