Answer:
the answer is A because if it is raised to the power greater than one and is added it will be greater than1
Quite a broad question. 10/2 you divide by 2 which equals 5. Is that your question?
No, you should have reduced each base to...
3^(3*2x) = 3^(2*(x-3))
and then you can cancel each base
3*2x = 2*(x-3)
6x = 2x-6
4x= -6
x = -3/2
C : B = D : E
6 : 5 = D : 3
D = 3.6
