Tolong jawab1.) (1/5)^-1 . (5/7)^-2 = …2.) (1/5)^-1 ÷ (5/7)^-2 = …

Penjelasan dengan langkah-langkah:

$({ frac{1}{5}) }^{ - 1} times ({ frac{5}{7}) }^{ - 2} = \ 5 times { (frac{7}{5} )}^{2} = \ 5 times frac{49}{25} = frac{49}{5} = 9 frac{4}{5}$

${( frac{1}{5}) }^{ - 1} div { frac{5}{7} }^{ - 2} = \ 5 div { frac{7}{5} }^{2} = \ 5 times frac{25}{49} = \ frac{125}{49} = 2 frac{27}{49}$
