Answer 1

Answer:

To prove : $\large{\sf \frac{(0.6) {}^{0} - (0.1) {}^{ - 1} }{( \frac{3}{8} ) {}^{ - 1} ( \frac{3}{2})^{3} + ( - \frac{1}{3}) {}^{ - 1}} =- \frac{3}{2}}$

Given that ;

$\implies \sf \frac{(0.6) {}^{0} - (0.1) {}^{ - 1} }{( \frac{3}{8} ) {}^{ - 1} ( \frac{3}{2})^{3} + ( - \frac{1}{3}) {}^{ - 1} } =- \frac{3}{2} \\ \\ \implies \sf \frac{1 - (0.1) {}^{ - 1} }{( \frac{3}{8} ) {}^{ - 1} ( \frac{3}{2})^{3} + ( - \frac{1}{3}) {}^{ - 1} } = - \frac{3}{2} \\ \\ \implies \sf \frac{1 - \frac{10}{1} }{( \frac{8}{3})( \frac{27}{8}) + ( - 3) } = - \frac{3}{2} \\ \\ \implies \sf \frac{1 - 10}{9 + ( - 3)} = - \frac{3}{2} \\ \\ \implies \sf - \frac{ 9}{6} = - \frac{3}{2} \\ \\ \implies \sf - \frac{3}{2} = - \frac{3}{2}$

Hence, it is proved.
