# Thread: Quick question, is my answer to this equation right?

1. ## Quick question, is my answer to this equation right?

Just say yes or no, pls don't tell me the answer or anything.

Question: 6x = (1/216)3-x

My answer: 2.25

Is this right?

2. ## Re: Quick question, is my answer to this equation right?

plugging this in it's clearly not correct.

There does appear to be a simple rational answer though. Try again.

3. ## Re: Quick question, is my answer to this equation right?

Hints:
$\dfrac{1}{216} = 6^{-3}$
$(n^a)^b = n^{ab}$

4. ## Re: Quick question, is my answer to this equation right?

Well, can you not plug in your 2.25 to see if correct?
If not, you're evidently not ready and need classroom help.
