Prove that ` |{:(ax,,by,,cz),(x^(2),,y^(2),,z^(2)),(1,,1,,1):}|=|{:(a,,c,,c),(x,,y,,z),(yz,,xz,,xy):}|` |
|
Answer» ` |{:(ax,,by,,cz),(x^(2),,y^(2),,z^(2)),(1,,1,,1):}|` Taking x,y,z common from`C_(1)C_(2) " and " C_(3)` respeectively we get ` |{:(a,,c,,c),(x,,y,,z),((1)/(x),,(1)/(y),,(1)/(z)):}|=|{:(a,,b,,c),(x,,y,,z),(yz,,xz,,xy):}|` (Taking xzy to `R_(3)`) |
