Make k the subject.

1/n = (k^+p^2/hg)^1/2

I have k=(hg/n^2-p^2) as the answer. But the book solved beyond my final solution,  and even had negative or positive sign in it.

Hi;

What comes after the k^?

If not, please modify this Latex so we know what the question is.

Thanks,

I'd say it's:

Or maybe with k and p both in the denominator.

hi Stefy,

I'm sure you are right so here goes:

Ebenezerson:  That looks a bit like what you had.  But k is not yet the subject. We must deal with the square root:

Hope that is what you were wanting.

note:

You must not just invert all the fractions to get

Try with numbers:

The  'k' squared plus the 'p' squared are on one platform, which is over the 'hg'.
And all of them are in a square root sign.

Thanks.

"equal to sign" and after the sign, there is a "negative or positive  sign" which confound me much.

I am curious, which answer did you like?

But the book has 1/n and a negative or positive sign after the "equl to sign", which is incomprehensible to me. Some help.

Please  solve it and you will definitly come across what I mean.

Is post #4 the right problem?

No.

Hi;

Have you considered using codecogs? Then you would be able to latex the problem.

the 'n' at the bottom carries a square why didnt you bring it?

Sorry, I am not getting an n^2 just an n. I had Mathematica do that and he is never wrong.

If we take it from the start. the n has to be squared when the square root at the R.H is taking away.

By the way what is mathematica I am curious to know.

But, when you clear k of the square, you will be taking a square root, which means n will lose the square.

Yes, the n^2 will disappear.

Mathematica is a computer program that is smarter than 1001 mathematicians.
