cube root(ln(5x-6) whats the inverse function

Solution

To find the inverse function of f(x)=ln(5x6)3f(x) = \sqrt[3]{\ln(5x - 6)}, follow these steps:

Step 1: Replace f(x)f(x) with yy

y=ln(5x6)3y = \sqrt[3]{\ln(5x - 6)}

Step 2: Swap xx and yy

x=ln(5y6)3x = \sqrt[3]{\ln(5y - 6)}

Step 3: Cube both sides to remove the cube root

x3=ln(5y6)x^3 = \ln(5y - 6)

Step 4: Exponentiate both sides to get rid of the natural logarithm

ex3=5y6e^{x^3} = 5y - 6

Step 5: Solve for yy

5y=ex3+65y = e^{x^3} + 6 y=ex3+65y = \frac{e^{x^3} + 6}{5}

Thus, the inverse function is: f1(x)=ex3+65f^{-1}(x) = \frac{e^{x^3} + 6}{5}
