World Vegan Day is celebrated every year on which of the

If a = 2 + √3, then the value of `(a^(6) + a^(4) + a^(2) + 1)/(a^(3))` is

In △ ABC, AB = AC. A circle drawn through B touches AC at D and intersect AB at P. If D is the midpoint of AC and AP = 2.5 cm, then AB is equal to:

 If f(x) = 3x² − 7x + 5, find f(2a) − 4f(a).

If 15a² + 1 = 20a, then find the value of {(9a² + 1)/25a²}

If x, y and z are real numbers such that (x-5)²+(y-8)²+(z-12)²= 0 then (x+y+z) is equal to

If a + (1/a) = 2, then find the value of (a⁵ + a³ + 6)/(7a – 5). 

If √b + (1/√b) = 8, then find the value of b + (1/b).
