If `b=sqrt3+iota`, then `b^3=?`

sqrt(5+12 iota)

If |AxxB| = sqrt3 A.B, then the value of |A+B| is

If |a|=7, |b|=11 and |a+b|=10 sqrt3 , then |a-b| is equal to

If a=2+sqrt(3)+sqrt(5) and b=3+sqrt(3)-sqrt(5) , then a^(2)+b^(2)-4a-6b-3 is equal to

If tan(A+B)=sqrt3 and tan A = 1, then tan(A-B) is equal to

If a=1 , b=sqrt3 and angleA = 30^(@) , find the value of the angle B :

Let |a|=7, |b|=11, |a+b|=10 sqrt3 What is the angle between (a+b) and (a-b) ?

If sin(A+B) = sqrt3/2 and tan(A-B)= 1/sqrt3 , then (2A + 3B) is equal to : यदि sin(A+B) = sqrt3/2 तथा tan(A-B)= 1/sqrt3 है, तो (2A + 3B) का मान क्या होगा ?
