Tolong bantu di jawab beserta penjelasannya ya!
Jawaban:
A 1 / 5⁴
B. 2³x²⁴y²¹ / x¹²y¹⁸
Penjelasan dengan langkah-langkah:
[tex]a. \: {5}^{ - 4} = \frac{1}{ {5}^{4} } \\ \\ b. \: ( \frac{ {x}^{4} {y}^{6} }{2 {x}^{8} {y}^{7} } ) ^{ - 3} \\ = \frac{ {x}^{4 \times ( - 3)} {y}^{6 \times ( - 3)} }{ {2}^{ - 3} {x}^{8 \times ( - 3)} {y}^{7 \times ( - 3)} } \\ = \frac{ { x}^{ - 12} {y}^{ - 18} }{ {2}^{ - 3} {x}^{ - 24} {y}^{ - 21} } \\ = \frac{ {2}^{3} {x}^{24} {y}^{21} }{ {x}^{12} {y}^{18} } [/tex]
