Q. Given the function y=3(6x+5)5, find dxdy in any form.Answer: dxdy=
Identify Function: Identify the function to differentiate.We are given the function y=3(6x+5)5 and we need to find its derivative with respect to x, which is denoted as dxdy.
Apply Chain Rule: Apply the chain rule for differentiation.The chain rule states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function. In this case, the outer function is u5 and the inner function is u=6x+5.Let's differentiate the outer function first, keeping the inner function as is.dxd[3(u)5] = 3×5×u5−1 = 15u4
Differentiate Inner Function: Differentiate the inner function.Now we differentiate the inner function u=6x+5 with respect to x.dxd[6x+5]=6
Multiply Derivatives: Apply the chain rule by multiplying the derivatives.Now we multiply the derivative of the outer function by the derivative of the inner function to get the overall derivative.dxdy=15u4×6
Substitute Inner Function: Substitute back the inner function.Replace u with the original inner function (6x+5).dxdy=15(6x+5)4×6
Simplify Expression: Simplify the expression.Now we simplify the expression by multiplying the constants.(dxdy=90(6x+5)4)
