(3/9 • 12)^2 - (2-3)^3

Answer 1

To simplify the expression, let's start by evaluating the numbers within parentheses:

(3/9 • 12) = (1/3 • 12) = 4

(2-3) = -1

Now, we can substitute these values back into the original expression:

(4)^2 - (-1)^3

Simplifying further:

16 - (-1)

The subtraction of a negative number is the same as adding its positive counterpart:

16 + 1

Therefore:

(3/9 • 12)^2 - (2-3)^3 = 17
