మన దగ్గర ఉంది,
\(\rm \frac{1}{x(xy)(xz)}+\frac{1}{y(yz)(yx)}+\frac{1}{z(zx)(zy)}\)
x = 1, y = 2, z = 3 ప్రతిక్షేపించండి
⇒ \(\rm \frac{1}{1(1-2)(1-3)}+\frac{1}{2(2-3)(2-1)}+\frac{1}{3 (3-1)(3-2)}\)
⇒ \(\frac{1}{(-1)(-2)}+\frac{1}{2(-1)}+\frac{1}{3(2)}\)
⇒ \(\frac{1}{2}-\frac{1}{2}+\frac{1}{6} = \frac{1}{6}\)
ఎంపిక (3) నుండి
\(\frac{1}{xyz} = \frac{1}{1\times 2\times 3} = \frac{1}{6}\)
∴ \(\rm\frac{1}{xyz}\) సరైన విలువ.
