Answer 1

Answer:

$\frac{a + b + c}{ {a}^{ - 1} {b}^{ - 1} + {b}^{ - 1} {c}^{ - 1} + {c}^{ - 1} {a}^{ - 1} } = abc \\ \\ \frac{a + b + c}{ \frac{1}{ab} + \frac{1}{bc} + \frac{1}{ca} } = abc \\ \\ \frac{a + b + c}{ \frac{c + a + b}{abc} } = abc \\ \\ \frac{a + b + c}{1} \times \frac{abc}{a + b + c} = abc \\ \\ abc = abc \\L.H.S = R.H.S \\ \\ \rightarrow \: hence,proved \\ \\ \red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
