**Length contraction equation determining v. what am i doing wrong???**

OK,

L=L*(1-v2/c2)1/2 (to the power of 1/2)

L=.75m L*=1.0m

now i need to find v and for the life of me i always end up with a value greater then c which is obviously impossible.

ill simplify to v=

L/L*=(1-v2/c2)1/2

(L/L*)squared = 1-v2/c2

1+(L/L*)squared = v2/c2

(1+(L/L*)squared )to the 1/2=v/c

c((1+(L/L*)squared )to the 1/2)=v

and thus i break the barrier of the speed of light and go back in time i guess...

any help?? asap please
