a+b=3, a-b=6 then find a,b values.

If the points P(-3,9) ,Q(a , b) and R(4 , - 5) are collinear and a + b=1, then find the values of a and b.

If b +c =3a , then find the value of cot.(B)/(2)cot.(C)/(2)

If a = 3 , b = 2 find the value of : a^a + b^b

If a = 3 , b = 2 find the value of: (a+b)^b

If a = 3, b = 2 find the value of (a-b) ^(b)

If a = 3 , b = 2 find the value of : a^b + b^a

If a = 3 , b = 2 find the value of : (a – b)^a . (a – b)^a or 3^5

If a = 3, b = 2 find the value of (a +b) ^(a)

If A = {2,3,4,5} B = {2,4,6,8} then find the value of A-B.
