Detailed Solution
Download Solution PDFகொடுக்கப்பட்டது:
x + y + z = 0
பயன்படுத்தப்பட்ட கருத்து:
x3 + y3 + z3 - 3xyz = (x + y + z)(x2 + y2 + z2)
x + y + z = 0 என்றால்
x3 + y3 + z3 - 3xyz = 0
எனவே, x3 + y3 + z3 = 3xyz
கணக்கீடு:
\({{x^2} \over (yz)}\) + \({{y^2} \over (xz)}\) + \({{z^2} \over (xy)}\)
⇒ \({{x^3 + y^3 + z^3} \over (xyz)}\)
⇒ \({{3xyz} \over xyz}\)
⇒ 3
∴ தேவையான பதில் 3.
