----------------------------------------------------------------------------

$(-2\frac{1}{1})^-^3-(-2\frac{1}{3})^-^2\\ (-\frac{5}{2})^-^3-(-\farc{7}{3})^-^2\\-\frac{8}{125}-\frac{9}{49}=-\frac{1517}{6125} \\=-0.247$

Answer 2

(-2+1/2) - ³ - (-2+1/3) - ²

First, let's simplify the terms within the parentheses.

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

Now we can substitute these values back into the original equation.

-1 1/2 - ³ - (-1 2/3) - ²

Next, we can simplify the exponents.

-1 1/2 - 27 - 1 2/3 - 4

Now we can add and subtract the fractions.

-3/2 - 27 - 5/3 - 4

To add and subtract these fractions, we need to find a common denominator. The least common multiple of 2 and 3 is 6.

-9/6 - 27 - 10/6 - 24/6

Now we can add and subtract the fractions.

-9/6 - 27 - 10/6 - 24/6 = -43/6 - 27 - 24/6

Now we can combine the fractions.

-43/6 - 27 - 4

To subtract the fractions, we need to find a common denominator.

-43/6 - 27 = -43/6 - 162/6 = -205/6

Now we can combine the whole numbers with the fraction.

-205/6 - 4 = -205/6 - 24/6 = -229/6

So, the final answer is -229/6.
