If (x-1/x)2 = 3, then the value of x6 + 1/x6 equals
If x = √5+1/√5-1 and y = √5-1/√5+1 , the value
of x2+xy+y2/x2-xy+y2 is
If x2 + y2+ 2x + 1 = 0, then the value of x31 + y35 is
If a+b+c = 0 then the value of
1/(a+b)(b+c) + 1/(b+c)(c+a) + 1/(c+a)(a+b) is
The simplified value of
(1-2xy/x2+y2) ÷ (x3-y3/x-y - 3xy) is
A right circular cylinder having diameter 21 cm & height 38 cm is full of ice cream. The ice cream is to be filled in cones of height 12 cm and diameter 7 cm having a hemispherical shape on the top. The number of such cones to be filled with ice cream is
