(root(6)(15-2sqrt(56)))*(root(3)(sqrt(7)+2sqrt(2)))=

(15-2sqrt(566))*(sqrt(7)-2sqrt(2)3)

Evaluate : x^(3)+3x-13, " if" x=root(3)(7+5sqrt(2))-(1)/(root(3)(7+5sqrt(2)))

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

The value of log_(2)(root(3)(2+sqrt(5))+root(3)(2-sqrt(5))) is equal to

(root(6)(5))(root(3)(2))(sqrt(3))(root(12)(6)) =

Simplify: (7sqrt(3))/(sqrt(10)+sqrt(3))-(2sqrt(5))/(sqrt(6)+sqrt(5))-(3sqrt(2))/(sqrt(15)+3sqrt(2))

If x=root(3)(7+5sqrt(2))-(1)/(root(3)(7+5sqrt(2))), then the value of x^(3)+3x-14 is equal to 1 b.0 c.2 d.4

If x=root(3)(7+5sqrt(2))-(1)/(root(3)(7+5sqrt(2))), then the value of x^(3)+3x-14 is equal to 1(b)0(c)2 (d) 4

Prove that root(3)(2+sqrt(5))+root(3)(2-sqrt(5)) is a rational number.
