Question

$\sqrt[3]{ \frac{?}{2197} } \: equal \: to \: \frac{11}{13}$
​

Answer 1

$\small\sf \bf \purple{ \sqrt[3]{ \frac{x}{2197} } = \frac{11}{13} \:}$

Step-by-step explanation:

Let the number we will find be 'x'.

$\small\sf \bf \purple{ \sqrt[3]{ \frac{x}{2197} } = \frac{11}{13} \:} \\ = > \frac{ \sqrt[3]{x} }{ \sqrt[3]{2197} } = \frac{11}{13} \\ = > \frac{ \sqrt[3]{x} }{13} = \frac{11}{13} \\ = > 13 \sqrt[3]{x} = 11 \times 13 \\ = > \sqrt[3]{x} = \frac{11 \times 13}{13} \\ = > \sqrt[3]{x} = 11 \\ = > x = 11 \times 11 \times 11 \times \\ = > x = 1331 \\ \\ therefore \: \sqrt[3]{ \frac{1331}{2197} } = \frac{11}{13}$
