Answer 2

Let's simplify the expression step by step:

(1/3)^(-3) - (-6/7)^0 + (1/2)^2 / 2

First, let's simplify the exponents:

(1^(-3))/3 - (-6/7)^0 + (1^2)/(2^2) / 2

Next, let's calculate the values of the expressions with exponents:

(1/1)/3 - 1 + 1/4 / 2

Simplifying further:

1/3 - 1 + 1/4 / 2

Next, let's simplify the division:

1/3 - 1 + 1/8

To add or subtract fractions, we need a common denominator. In this case, the common denominator is 24:

8/24 - 24/24 + 3/24

Now we can add the fractions:

(-16 + 3 + 3) / 24

-10 / 24

The fraction -10/24 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

-5/12

So, the simplified expression is -5/12.
