Question :

• What should be multiple ( 4/3 )^ -2. So that the product is equal to ( - 4/5 )^ -3

Solution :

Let be the number is x

According to question :

$\sf \implies \bigg(\frac{4}{3} { \bigg)}^{ - 2} \times x = \bigg( - \frac{4}{5}{\bigg)}^{ - 3} \\ \\\sf \implies\bigg(\frac{3}{4} { \bigg)}^{2} \times x = \bigg( - \frac{5}{4}{\bigg)}^{3} \\ \\\sf \implies \frac{9}{16} \times x = - \frac{125}{64} \\ \\\sf \implies x = - \frac{125}{64} - \frac{9}{16} \\ \\\sf \implies x = \frac{ - 125 - 36}{64} \\ \\ \sf \implies x = \frac{261}{64}$
