1/ ^3 sqrt x^x-6

OpenStudy (anonymous):

Can you type that with the equation editor?

OpenStudy (anonymous):

\[1/^3\sqrt{x^-6}\]

OpenStudy (anonymous):

@jwhite12

OpenStudy (anonymous):

\[\frac{ 1 }{ \sqrt[3]{x-6} }\] ? What are you supposed to do with that? What's the question?

OpenStudy (anonymous):

Simplify the given expression to rational exponent form and justify each step by identifying the properties of rational exponents used. All work must be shown. @jwhite12

OpenStudy (anonymous):

Taking the third root of something is the same as raising it to the 1/3 power.

OpenStudy (anonymous):

I'm sorry but I don't get what you said. What do you mean by the third root of something?

OpenStudy (anonymous):

@jwhite12

OpenStudy (anonymous):

\[\sqrt[3]{ }\] is the third root

OpenStudy (anonymous):

So your problem is taking the third root of (x-6), in the denominator

OpenStudy (anonymous):

To solve it what I did was \[1/x^-6/3\] then \[1/x^-2\] Im confused about the 1 in the numerator. @jwhite12

OpenStudy (anonymous):

I'm confused about what step you did there. Did you try to divide by 3?

OpenStudy (anonymous):

I divided the -6 by 3 @jwhite12

OpenStudy (anonymous):

You can't do that. They just want you to rewrite the radical expression as an exponential expression. So \[\sqrt[3]{x-6}=(x-6)^{\frac{ 1 }{ 3 }}\]

OpenStudy (anonymous):

The -6 is an exponent of x. @jwhite12

OpenStudy (anonymous):

Ohhhhh ok. Sorry, I couldn't tell what your exponents were. \[\sqrt[3]{x^{-6}}\]

OpenStudy (anonymous):

Ok, I'm with you. Yes, you were right then. But I think can do one more step.

OpenStudy (anonymous):

\[\frac{ 1 }{x ^{\frac{ -6 }{ 3 }} }=\frac{ 1 }{x ^{-2} }\] That's what you had, right?
