1.	P = xy, Q = yz, R = zx then PQR = ………………… A) x2 y2 z2 B) xy2 z2 C) xy zD) \(\frac{x^2y^2}{z^2}\)
Answer» Correct option is A) x² y² z² Correct option is (A) x² y² z² P = xy, Q = yz, R = zx. Then PQR = (xy) (yz) (zx) \(=(x\times x)(y\times y)(z\times z)\) = \(x^2y^2z^2\).

P = xy, Q = yz, R = zx then PQR = ………………… A) x2 y2 z2 B) xy2 z2 C) xy zD) \(\frac{x^2y^2}{z^2}\)

Answer»

Correct option is A) x² y² z²

Correct option is (A) x² y² z²

P = xy, Q = yz, R = zx.

Then PQR = (xy) (yz) (zx)

\(=(x\times x)(y\times y)(z\times z)\)

= \(x^2y^2z^2\).
