1)Without evaluating the angles A and B,find the value of tan(A+2B),

given tanA = 2/3 and tanB =1/3.

2)Simplify (x/y)powerof2/3 . xpowerof3/ypowerof4

3)Findallangles between 0deg and 360deg inclusive which satisfy the equation : 3cossquartA - 2cosA - 1 = 0

4)find the value of x when : log(base2)x + log(base8)x = 4/3

BIG thanks!!!
