Answer: $\frac{\sqrt{3}}{2}$

Hint: $\sin ^{-1} x+\cos ^{-1} x=\frac{\pi}{2}$

Solution:Given , $4\cos^{-1}x+\sin^{-1}x=\pi$

$\sin ^{-1} x+\cos ^{-1} x=\frac{\pi}{2}$

$4 \cos ^{-1} x+\frac{\pi}{2}-\cos ^{-1} x=\pi$

$3 \cos ^{-1} x=\pi-\frac{\pi}{2}$

$\cos ^{-1} x=\frac{\pi}{6}$

$\mathrm{x}=\frac{\sqrt{3}}{2}$
