40.sqrt(6+sqrt(6+sqrt(6+...oo)))" is equal to "

Evaluate : (a) sqrt(xsqrt(xsqrt(x.....oo))) (b) sqrt(6+ sqrt(6 + sqrt(6 + ......oo))) (c) sqrt(a^(3)root(3)(b sqrt(a^(3) root(3)(b.......oo))))

The value of log_(2)(sqrt(17+2sqrt(6))-sqrt(7-2sqrt(6))) is equal to

(6 + sqrt6)(6 - sqrt6)

Given that: sqrt(3) = 1.732, (sqrt(6) + sqrt(2)) / (sqrt(6)-sqrt(2)) is equal to:

sqrt(2)+sqrt(3)+sqrt(4)+sqrt(6) is equal to

sqrt(6) xx sqrt(8) is equal to
