(a) `sqrt15xxsqrt35.`
(b) `2sqrt3 div3sqrt27.`
(c ) Muliple `root(3)(3)" by " root(4)(2).`
(d) Divide `""root(6)(5)" by "root(3)(10).`

(a) Divide 1 by (sqrt7 -1) (b) Divide 3 root4(5) " by " 6 root4(5)

Compare : (i) root(6 )(15) and root(4)(12)" (ii) "sqrt(24) and root(3)(25)

sqrt(2)times root(3)(2)times root(6)(2)

root(3)(26-15sqrt(3))=

The value of (root(3)(3.5) + root(3)(2.5)) { (root(3)(3.5) )^2 - root(3) (8.75) + ( root(3)(2.5))^2} is

Prove that sqrt(" "){8 sqrt3 + sqrt5 + sqrt(" ")(8 -2 sqrt15)}= 3 root(4)(3)

(a) If x gt a, y gt b and x + y = a + b , then find which one of (sqrtx + sqrty) and (sqrta + sqrtb) is greater ? (b) Which one of the two (sqrt21 + sqrt11) and (2sqrt5 + 2 sqrt3) is greater ? (c) Which one is greater root(3)(4) and root(4)(5) ? (d) Find the greatest and least numbers : 2 sqrt2, 3 root(3)(2), 2 root(4)(3), 2 root(6)(7)

root(3)(1+sqrt(2)).root(6)(3-2sqrt2)= ?
