Could someone help me with understanding the answer conversion to log form? Im not sure how the answer from sinh(cosh^-1sqrtx) turns into (x-1)^1/2 as shown.

Also, for some reason my photos always end up sideways on here. Orientation is correct in the base file.

sinh(arcosh√x)
let θ = arcosh√x

coshθ =√x
cosh2θ = x
cosh2θ - 1= x -1
sinh2θ = x -1
sinhθ = √(x -1)
sinh(arcosh√x) = √(x -1)
