निम्नलिखित के अवकलज ज्ञात कीजिए।
(i) `2x-3/4` (ii) `(5x^(3)+3x-1)(x-1)`
(iii) `x^(-3)(5+3x)` (iv) `(3-6x^(-9))`
(v) `x^(-4)(3-4x^(-5))` (vi) `2/(x+1)-(x^(2))/(3x-1)`

Answer

(i) 2 (ii) `20x^(3)-15x^(2)+6x-4` (iii) `(-3)/(x^(4))(5+2x)` (iv) `15x^(4)+24/(x^(5))`
(v) `(-12)/(x^(5))+36/(x^(10))` (vi) `(-2)/((x+1)^(2))-(x(3x-2))/((3x-1)^(2)0`
