\text{Consider the function}\\
\\
f(x)=6x^3-3\\
\\
\text{let }y=f(x), \text{ so we have}\\
\\
y=6x^3-3\\
\\
\text{now in order to find the inverse of the function, first we interchange x and y}\\
\text{so we get}\\
\\
x=6y^3-3

\text{now we will solve for y again and that will give the required inverse function.}\\
\text{so first we add 3 both sides to get}\\
\\
x+3=6y^3\\
\\
\text{now divide both sides by 6 to get}\\
\\
\frac{x+3}{6}=y^3\\
\\
\text{now take cube root both sides to get}\\
\\
\sqrt[3]{\frac{x+3}{6}}=\sqrt[3]{y^3}

\Rightarrow \sqrt[3]{\frac{x+3}{6}}=y\\
\\
\Rightarrow y=\sqrt[3]{\frac{x+3}{6}}\\
\\
\text{hence the inverse of the function is: }\\
\\
f^{-1}(x)=\sqrt[3]{\frac{x+3}{6}}

PLEASE HELP!!
madam [21]

Answer:

k=2/3

Step-by-step explanation:

Step 1:

Step 1 in solving the exponential equations is re-writing the base same as other side of the equation

so,

25^{3k}=625\\=> 25^{3k}=25^2

Step 2:

Second step is equating the exponents

The rule used is:

If\ B^m=B^n\ then\ m=n

So in this case

3k=2\\k = \frac{2}{3}

So the solution is:

k=2/3 ..
