# Math Help - Isolating

1. ## Isolating

M = K / ((1 - (V^2/C^2) )^1/2)

Isolate V.

I just don't get this one

2. ## Re: Isolating

Swuare both sides, multiply by C^2 and see where that gets you...

Thanks man!

Chazzy, the Wolfram solution contains SQRT(c^2 m^2 - c^2 k^2):
any idea why they don't simplify that to: cSQRT(m^2 - k^2) ?

No idea, but it wouldn't be *just* C, but rather
|C|

Since c is the speed of light, it would be just c.

Slow down, Alexander !

No, c is the cardinality of the real numbers.
