Question

pls, solve this. whoever solves this i will mark them the brainliest.

Answer 1

Step-by-step explanation:

$\sqrt[3]{\frac{250}{432} } - \sqrt[3]{\frac{343}{729} } \\ = \sqrt[3]{\frac{125}{216} } - \sqrt[3]{\frac{7 \times 7 \times 7}{9 \times 9 \times 9} } \\ = \sqrt[3]{\frac{5 \times 5 \times 5}{6 \times 6 \times 6} } - \frac{7}{9} \\ = \frac{5}{6} - \frac{7}{9} \\ lcm \: of \: 6 \: and \: 9 = 18 \\ = \frac{5}{6} \times \frac{3}{3} - \frac{7}{9} \times \frac{2}{2} \\ = \frac{15}{18} - \frac{14}{18} \\ = \frac{1}{18}$
