Answer:


(1)/(11)

Explanation:

First, remember that the ln function is just a log function with a base of e. Here's how it looks


ln(x) =log_(e)(x)


ln(\sqrt[11]{e} ) = log_(e)(\sqrt[11]{e} )

We can take this one step further if we realize that we can rewrite the square root as a simple power to a fraction!


log_(e)(e^{(1)/(11) } )

Solving the equation above is really simple. All that function is really saying is can we raise e to some number, where the result would be e^(1/11)? In other words find x.


e^(x) = e^{(1)/(11) }

Well x has to be 1/11 in that case. And that ends up being our final answer.


log_(e)(e^{(1)/(11) } ) = (1)/(11)

Answer:

1/11

Explanation:

We are asked to find the natural log of


\sqrt[11]{e}

Convert to fractional exponent


ln(e {}^{ (1)/(11) } )

Apply Log of Power rule


(1)/(11) ln(e)

Natural log of e is 1 so


(1)/(11) * 1 = (1)/(11)
