If `(2^(2) + 3^(2) - 4^(2)) -:((3)/(2))^(2) = (-a)/(b) `, then `a + b` is equal to `(G.C.D(a,b)=1)`.

If 2^(n+4)-2^(n+2)=3, then n is equal to a.0 b.2c.-2d.-1

If (4b^(2)+(1)/(b^(2)))=2, then (8b^(3)+(1)/(b^(3)))=? (a) 0 (b) 1 (c) 2 (d) 5

If (a+(log)_(4)3)/(a+(log)_(2)3)=(a+(log)_(8)3)/(a+(log_(4)3)=b, then b is equal to (1)/(2)(2)(2)/(3)( c) (1)/(3)( d ) (3)/(2)

If a+b=1 , then a^(4)+b^(4)-a^(3)-b^(3)-2a^(2)b^(2)+ab is equal to :

If (2a+3b) (2c -3d) = (2a-3b) (2c+3d) then

If a,b,c,d are in G.P.prove that: (a^(2)+b^(2)),(b^(2)+c^(2)),(c^(2)+d^(2)) are in G.P.(a^(2)-b^(2)),(b^(2)-c^(2)),(c^(2)-d^(2)) are in G.P.(1)/(a^(2)+b^(2)),(1)/(b^(2)+c^(2)),(1)/(c^(2)+d^(2)) are in G.P.(a^(2)+b^(2)+c^(2)),(ab+bc+cd),(b^(2)+c^(2)+d^(2))

If A-B=pi/4, then (1+tan A)(1-tan B) is equal to 2 b.1 c.0 d.3
