Rewrite in simplest radical form Show each step of your process.

\[\frac{ 1 }{ x ^{\frac{ -3 }{ 6 }}}\]

Help. I think for the first step I'd have to divide by the reciprocal to get rid of the negative?

Yes that would be the first step.
anonymous
  • anonymous
Okay so I have that part, where do I go next? .-.
anonymous
  • anonymous
are you doing this on a graph or?
anonymous

A graph? No...

just paper?

Okay i understand now. First, you can reduce 3/6
anonymous
  • anonymous
1/2
anonymous
  • anonymous
but it is -1/2 because of the negative 3

Do you know how to deal with a negative exponent?
anonymous
  • anonymous
Okay you seriously just confused me, can you walk me through each one of those steps... I'm still at the beginning.
anonymous
  • anonymous
signs okay do you have to write it all out or can i just give you the answer?
anonymous
  • anonymous
\[\frac{ 1 }{ x ^{\frac{ -1 }{ 2 }} }\] After reducing this is where we're at correct?
anonymous
  • anonymous
correct
anonymous
  • anonymous
No, I need to write it all out, to get to simplest radical form.

Just like the rule above of negative exponents works, this one also works: 1a−n=an A negative exponent in the denominator, is a positive exponent in the numerator.
anonymous
  • anonymous
Notice we have a similar thing to this last rule. We have a fraction with 1 over. Then in the denominator we have x to a negative exponent. It changes into just x to the positive exponent in the numerator, and the denominator disappears.
anonymous
  • anonymous
So wait it's just \[\frac{ 1 }{ x ^{1} }\]
anonymous
  • anonymous
?

  • anonymous
ok look

this is your final answer :)
anonymous
  • anonymous
Oh okay, I see now. You confused me by saying that the denominator disappears.
anonymous
  • anonymous
sorry
anonymous
  • anonymous
I thought you meant in the exponent.
anonymous
  • anonymous
lol no ill try to be more clear next time :)
anonymous
  • anonymous
Erm is there a certain name for that rule up above? My teacher will want to know that.
anonymous
  • anonymous
I mean no not really, Im pretty sure if you just leave it as it she will understand no rule :)
anonymous
  • anonymous
Okay, Thanks. :)
anonymous
  • anonymous
no problem ^.^

a−n=1an a1n=a√n i was looking at this yesturday and realized these are your rules
