2. Turunan pertama dari f(x)=5x^4 +x(√x)+(6/( (√×)))−sin x−2cos x+5 adalah... a. f^1 (x)=20x^3 +(3/2)(√x)+(6/(×(√×)))+cos x−2sin x b. f^1 (x)=20x^3 +(3/2)(√x)−(3/(x(√x)))−cos x+2sin x c. f^1 (x)=20x^3 +(3/2)(√x)−(1/(x(√x)))−cos x+2sin x d. f^1 (x)=20x^3 +(2/3)(√x)−(3/(x(√x)))+cos x+2sin x e. f^1 (x)=20x^3 +(3/2)(√x)−(1/(x(√x)))+cos x+2sin x

It is Indonexia language that means “the first derivative of f(x)=5x^4 +x(√x) +(6/( (√x)))−sinx−2cosx+5 is”

$$\mathrm{It}\:\mathrm{is}\:\mathrm{Indonexia}\:\mathrm{language}\:\mathrm{that}\:\mathrm{means} \\ $$$$``\mathrm{the}\:\mathrm{first}\:\mathrm{derivative}\:\mathrm{of}\:\mathrm{f}\left(\mathrm{x}\right)=\mathrm{5x}^{\mathrm{4}} +\mathrm{x}\sqrt{\mathrm{x}} \\ $$$$+\frac{\mathrm{6}}{\:\sqrt{\mathrm{x}}}−\mathrm{sinx}−\mathrm{2cosx}+\mathrm{5}\:\:\:\:\mathrm{is}'' \\ $$
