Correct Answer - A
`(6^(2)+7^(2)+8^(2)+9^(2)+10^(2))/(sqrt(7+4sqrt(3)-sqrt(4+2sqrt(3))))`
`= gt (6^(2)+7^(2)+8^(2)+9^(2)+10^(2))/(sqrt((2+sqrt(3))^(2))-sqrt((sqrt(3)+1)^(2)))`
`implies(6^(2)+7^(2)+8^(2)+9^(2)+10^(2))/(2+sqrt(3)-sqrt(3)-1)`
`implies 6^(2)+7^(2)+8^(2)+9^(2)+10^(2)`
`implies36+49+64+81+100`
`implies330`
