-(3^(-2)) = -0.111111111
It is: 3-1*3-2 = 1/27
48
3-2 = 9
It will be 1/27 .

-(3^(-2)) = -0.111111111
A negative exponent is 1 over the base to the power of the absolute value of the exponent. For example 2 to the power of -1 is 1/2, 2 to the power of -2 is 1/4, or (1/2) squared, and 2 to the power of -3 is 1/8, or (1/2) cubed.
It is: 3-1*3-2 = 1/27
1/9
-3^2 = 9 -(3^2) = -9
48
3-2 = 9
(-2/3)^2 = 4/9
I believe that the answer is 2 over 3
a3*a-2 = a(3-2) = a
