`C=\sqrt{4+\sqrt{5\sqrt{3}+\sqrt{5+\sqrt{48-10\sqrt{7+4\sqrt{3}`
`C=\sqrt{4+\sqrt{5\sqrt{3}+5+\sqrt{48-10\sqrt{(2+\sqrt{3})^2}`
`C=\sqrt{4+\sqrt{5\sqrt{3}+5+\sqrt{48-10\sqrt{(2+\sqrt{3})}`
`C=\sqrt{4+\sqrt{5\sqrt{3}+5\sqrt{28-10\sqrt{3}`
`C=\sqrt{4+\sqrt{5\sqrt{3}+\sqrt{20-10\sqrt{3}`
`C=\sqrt{4+\sqrt{5\sqrt{3}+5\sqrt{(5-\sqrt{3})^2}`
`C=\sqrt{4+\sqrt{5\sqrt{3}+5\sqrt{(5-\sqrt{3})}`
`C=\sqrt{4+\sqrt{5\sqrt{3}+25-5\sqrt{3}`
`C=\sqrt{4+5}`
`C=3`
