How to do (1/4)^(-1/2)?
Hold on I will help
Ok thanks
Okay first you have to simplify the expression
How would I do that?
Your awnser would be -1/8
The answer in my book says 2
Then thatwould be your awnser
I have to show my work though and I'm not sure how to get it
For the work just put you have to simplify the expression by breaking it down
\[x^{-a} = \frac{1}{x^a}\]
I know how to do negative exponents it's just the fraction part is confusing me
oh okay. you have to convert exponent to a radical
\[x^{\frac{1}{2}} =\sqrt{x}\]
Oh okay. I think I get it. Would you make it sq rt 4 and then get 2
\[\large x^{\frac{m}{n}} = \sqrt[n]{x^m}\]
well, first of all how would you rewrite the expression with positive exponent?
4^1/2?
remember: the entire fraction raised to a negative exponent
\[\frac{ 1 }{ \sqrt{\frac{1}{4}} }\] \[\frac{ 1 }{(4)^ \frac{1}{2} } \rightarrow 1 \times \frac{ 4^\frac{ 1 }{ 2 } }{ 1 } \rightarrow \sqrt{4}=2\] your answer is correct: make sure 1/ (1/4)^(1/2)
Oh okay. That makes sense. Thanks for the help.
correction: \[\frac{ 1 }{ (\frac{ 1 }{ 4 } )^\frac{ 1 }{ 2 }}\]
you're welcome. good job.
