Evaluate--
(1/81)^ -1/4

I know that the correct answer is 3.. I got 9.. I can show my work if you want

3^4=81 as my hint

Huh?? O.o

Realize that (1/81)^-1/4=(81)^1/4

Yes I know that

Them you are good
I just told you 81=3^4

So why do you get 9

If your saying 3^4 is the answer that is incorrect

No iIdidn't say it is the answer just one step before the answer

Why did I make it 3^4 if you think about it

The answer is 3 like you said I'm just giving the why it is the answer

Oh.. Um not sure

Lol incorrect footsteps that's why it is wrong

How? I followed the example that I was given

Didn't I jut wrote (1/81)^-1/4=(81)^1/4
So we have (3^4)^1/4

I thought you understood that step

I understand changing -1/4 to 1/4... I did that in the first step.

Now you have something like (a^n) ^m
Which is a^(nxm) rule

You did but you didn't flip the fraction

You should have used 3^4 not 9^2

That's exponent rule my dear

Even if you used 9^2 You still end up with (9^2)^1/4=9^1/2=3

It is ni5 square root it 4th root

Sorry I couldn't help more since I'm in the phone otherwise I would try to before precise

Try to be precise *
