यदि y = x2 + \(\rm 3x^{1\over2}\)- \(\rm 5x^{2\over5}\) है, तो y'' का मान ज्ञात कीजिए।
1
y'' = 2 + \(3\over4\)x\(-{3\over2}\) - \(6\over 5\)x\(-{8\over5}\)
2
y'' = 2 - \(3\over4\)x\(-{3\over2}\) - \(6\over 5\)x\(-{8\over5}\)
3
y'' = 2 - \(3\over4\)x\(-{3\over2}\) + \(6\over 5\)x\(-{8\over5}\)
4
y'' = 2 + \(3\over4\)x\(-{3\over2}\) + \(6\over 5\)x\(-{8\over5}\)
