sqrt(56)+sqrt(56+sqrt(56+sqrt(56)))

sqrt(sqrt(63)+sqrt(56))=

(sqrt(56+sqrt(56+sqrt(56+...))))/2^(2)=?

If a= (sqrt(5) + sqrt(2))/(sqrt(5) -sqrt(2)) and b = (sqrt(5)-sqrt(2))/(sqrt(5)+sqrt(2)) show that 3a^(2) + 4ab -3b^(2) = 4 +(56)/(3) sqrt(10)

If x=sqrt(56+sqrt(56+sqrt(56+....oo))) and y=sqrt(56-sqrt(56-sqrt(56....)) then which of the ) followinig true?

log_((4)/(3))(56+(sqrt(56+sqrt(56+sqrt(56+......oo))))/(sqrt(64sqrt(64sqrt(64.....oo)))))

Simplify: sqrt(216)-5 sqrt(6)+sqrt(294)-3/(sqrt(56))

The distance between the parallel planes x+2y-3z=2 and 2x+4y-6z+7=0 is (A) 1/sqrt(14) (B) 11/sqrt(56) (C) 7/sqrt(56) (D) none of these

The distance between the parallel planes x+2y-3z=2 and 2x+4y-6z+7=0 is (A) 1/sqrt(14) (B) 11/sqrt(56) (C) 7/sqrt(56) (D) none of these

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