I think that you left out a plus sign Angelica  

$$\frac{1}{100,000,000,000}$$

I put the commas in so I could count the zeros.  there are 11 zeros so there is no perfect square root (because it is an odd number.)

$$\sqrt{\frac{1}{100,000,000,000}}\\\\
=\sqrt{\frac{1}{10,000,000,000\times 10}}\\\\\
=\frac{1}{\sqrt{10,000,000,000\times 10}}\\\\
=\frac{1}{\sqrt{10,000,000,000}\times \sqrt{10}}}\\\\
=\frac{1}{100,000\sqrt{10}}}\\\\
=\frac{1}{100,000\sqrt{10}}}\times\frac{\sqrt{10}}{\sqrt{10}}\\\\
=\frac{\sqrt{10}}{1,000,000}}\\\\$$

you are welcome Dragon 

Adrienne if you want to do these you can use the 'calculation ' button above .

It is like the forum version of the calculator.

$${{\mathtt{399}}}^{{\mathtt{3}}}{\mathtt{\,\times\,}}{\mathtt{23}} = {\mathtt{1\,460\,987\,577}}$$

That way it is a bit clearer what you have done.     

Ah hA Quinn,  I have seen this question before.  

When you have to use an equation you can look at it if you need to, BUT NEVER look at it as you write it unless you are just committing it to memory.  If you actually need to use it.  LOOK, take it away, write it THEN check you got it right.

It is not really physics but we do not have a chemistry category.

No ,I think there are 2 pints in a quart so 6 pints in 3 quarts.  :)

I just had to "write more" or it wouldn't accept my answer.  

Yes I had fun with this problem quinn.

But it is better if you get the question right in the first place.  I liked the Extra brackets that you put in second time round, then we know we have not misinterpreted.

I have included this problem in the next "End of Day Wrap" that i  write.  I invite you to read my wrap.  I write one most nights.

Here is the address of yesterday's one.  They are kept in with the sticky topics.  :)

Much of this is WAY OVER your head Dragon.  Your teacher cannot seriously expect you to do it!!
