This question might be written two different ways resulting in two different answers. It depends on how, exactly, it is written:

(-3)^2 (the symbol ^ indicates the power)

= -3 x -3

= 9

OR

-(3)^2

= - (3 x 3)

= -9

If there are no brackets on the question at all then I would assume that the second one is the correct one.

3-2 = 1/9 or one ninth. Expressed as a decimal, this is equal to 0.1 recurring (that is, 0.1111...)
