Q. Find the derivative of the following function.y=log6(6x6)Answer: y′=
Identify Function and Base: Identify the function and the base of the logarithm.We are given the function y=log6(6x6), where the base of the logarithm is 6.
Apply Change of Base Formula: Apply the change of base formula to convert the logarithm to a natural logarithm.The change of base formula is logb(a)=ln(b)ln(a). Using this, we can rewrite the function as y=ln(6)ln(6x6).
Differentiate Using Chain Rule: Differentiate the function using the chain rule.The derivative of ln(u) with respect to x is u1⋅dxdu. Here, u=6x6. So, we need to find the derivative of u with respect to x, which is dxdu=dxd(6x6).
Calculate Derivative of u: Calculate the derivative of u=6x6 with respect to x. Using the power rule, the derivative of xn with respect to x is n⋅x(n−1). Therefore, dxdu=6⋅6⋅x(6−1)=36x5.
Substitute Derivative into y: Substitute the derivative of u into the derivative of y. The derivative of y is then y′=6x61⋅ln(6)36x5.
Simplify Expression: Simplify the expression.We can cancel out an x5 from the numerator and denominator, which gives us y′=x36/ln(6).
Further Simplify: Further simplify the expression.We can rewrite the derivative as y′=x⋅ln(6)36.
