In our syllabus, there are three methods in differentiation namely chain rule, product rule and quotient rule.

• True

• False

Differentiate

 $y=\left(3x^5-8\right)^4$  

•  $\frac{dy}{dx}=60x^4\left(3x^5-8\right)^3$  
  

•  $\frac{dy}{dx}=15x^4\left(3x^5-8\right)^3$  

•  $\frac{dy}{dx}=15x^5\left(3x^5-8\right)^3$  

•  $\frac{dy}{dx}=60x^5\left(3x^5-8\right)^4$  

Differentiate

 $y=\left(9x^2+6\right)^3$  

•  $\frac{dy}{dx}=18x\left(9x^2+6\right)^2$  
  

•  $\frac{dy}{dx}=54x^{ }\left(9x^2+6\right)^2$  

•  $\frac{dy}{dx}=54x^2\left(9x^2+6\right)^3$  

•  $\frac{dy}{dx}=18x^2\left(3x^5-8\right)^2$  

Differentiate

 $y=\left(12+x^5\right)^6$  

•  $\frac{dy}{dx}=18x\left(9x^2+6\right)^2$  
  

•  $\frac{dy}{dx}=54x^{ }\left(12+x^5\right)^2$  

•  $\frac{dy}{dx}=30x^4\left(12+x^5\right)^5$  

•  $\frac{dy}{dx}=18x^2\left(3x^5-8\right)^2$  

Differentiate

 $y=\left(6x^2+4\right)^{-5}$  

•  $\frac{dy}{dx}=-60x\left(6x^2+4\right)^{-4}$  
  

•  $\frac{dy}{dx}=60x\left(6x^2+4\right)^{-6}$  

•  $\frac{dy}{dx}=60x\left(6x^2+4\right)^{-4}$  

•  $\frac{dy}{dx}=-60x\left(6x^2+4\right)^{-6}$
