Evaluate :
(i) `(2^(38) + 2^(37) + 2^(36))/(2^(39) + 2^(38) + 2^(37))` (ii) `[(64^((1)/(2)))^((1)/(6))]^(2)`

Evaluate : 37^(2) - 36^(2)

Evaluate (i) (32)^((1)/(5)) +(-7)^(0) + (64)^((1)/(2)) (ii) (0.00032)^(-(2)/(3)) (iii) ((64)/(125))^(-(2)/(3)) .

Evalute: (38)^(2) - (37)^(2) (75)^(2)-(74)^(2) (92)^(2) -(91)^(2) (105)^(2)-(104)^(2) (141)^(2) - (140)^(2) (218)^(2) -(217)^(2)

(37^(3)-28^(3))/(37^(2)+37.28+28^(2))=

Evaluate: (64^((a)/(6)))/(4^(a))times(2^(2a+1))/(2^(a-1))

If x^(2) + y^(2) = 37 and xy = 6, find x+y
