#x = 0.99#

Explanation:

I'm assuming you wish for us to solve

#2 + logsqrt(1 + x) + 3logsqrt(1 -x) = logsqrt(1 - x^2)#

We must apply the logarithm laws:

#2 + logsqrt(1 + x) + 3logsqrt(1 - x) = logsqrt((1 + x)(1 -x))#

#2 + 1/2log(1+ x) + 3/2log(1 -x) = 1/2log((1 + x)(1 -x))#

#2 + 1/2log(1+ x) + 3/2log(1- x) = 1/2log(1 + x) + 1/2log(1 -x)#

#log(1 - x) = -2#

#10^-2=1-x#

#x=1-10^-2#

#x = 1-1/100#

#x=99/100=0.99#

Hopefully this helps!
