Then find out the value of (x²+y²-xy)/(x²+y²+xy)

 `sqrt(sqrt(17+sqrt(17+sqrt(17)) ... prop)`   = ?

If (2a + b)/(3b - 2b) = 13/2 then 'b' is what percent of 'a'?

If x² – 10x + 20 = 0, then find the value of (x – 3)² + 1/(x – 3)²

The coefficient of ‘b²’ in (3a + b)³ is

If (a² + 1/a²) = 18, then find the value of (a³ - 1/a³).

What is the value of (a² + b²+4c²- ab-2bc-2ca) (a + b+2c):

√4096 + √(?) + 13 – 29 = 148
