Differentiate with respect to x:(3 – 4x)5

1.	Differentiate with respect to x:(3 – 4x)5
Answer» Chain rule: If y = f(t) and t = g(x) then dy/dx = dy/dt x dt/dx d/dx(3 – 4x)⁵ = 5(3 – 4x)⁴ * d/dx(3 – 4x) = 5(3 – 4x)⁴ * ( – 4) = – 20(3 – 4x)⁴

Answer»

Chain rule:

If y = f(t) and t = g(x) then dy/dx = dy/dt x dt/dx

d/dx(3 – 4x)⁵ = 5(3 – 4x)⁴ * d/dx(3 – 4x)

= 5(3 – 4x)⁴ * ( – 4)

= – 20(3 – 4x)⁴
