me assume that junk shood be

[8-sqrt(7)] / [8-7*sqrt(6)]

yu need tu multipli it bi [8 +7*sqrt(6)] / [8+7*sqrt(60]

Then bottom become [8-7sqrt(6)]*[8+7sqrt(6)....[8*8 -49*6]...64-294....-230

top become [8-sqrt(7)]*[8+7*(sqrt7)]...64-8*sqrt(7)+7*8*sqrt(7) -7*7...64 -49 +56sqrt(7)-8*sqrt(7)

top=15+48*sqrt(7)

top/bottom=[15+48*sqrt(7)] /-230

or -0.0652173 -0.2086956*sqrt(7)
