Q. Find the derivative of the following function.y=log6(−8x6)Answer: y′=
Understand and Apply Chain Rule: Understand the function and apply the chain rule.The function y=log6(−8x6) is a logarithmic function with base 6. To find the derivative, we need to use the chain rule, which 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.
Differentiate Outer Function: Differentiate the outer function.The outer function is log6(u), where u=−8x6. The derivative of log6(u) with respect to u is u⋅ln(6)1 according to the logarithmic differentiation rule.
Differentiate Inner Function: Differentiate the inner function.The inner function is u=−8x6. The derivative of −8x6 with respect to x is −48x5 by using the power rule.
Apply Chain Rule: Apply the chain rule.Now we multiply the derivative of the outer function by the derivative of the inner function to get the derivative of the composite function.y′=−8x6⋅ln(6)1⋅(−48x5)
Simplify Expression: Simplify the expression.We can simplify the expression by multiplying the constants and combining like terms.y′=−8x⋅ln(6)−48⋅x5y′=x⋅ln(6)6
