Question

-(-1/3)²-(1/2)²+1срочноооор

Answer 1

$- \frac{1}{9} - \frac{1}{4} = - \frac{4}{36} - \frac{9}{36} = - \frac{13}{36} + 1 = \frac{23}{36}$

Answer 2

Ответ:

-(-1/3)²-(1/2)²+1 = -(-1/3 × (-1/3)) - (1/2 × 1/2) + 1 = -1/9 - 1/4 + 1 = -1/9 × 4/4 - 1/4 × 9/9 + 1 × 36/36 = -4/36 - 9/36 + 36/36 = -13/36 + 36/36 = -23/36.

Answer 3

Sure, let's solve the expression step by step:

1. Begin with the first term: -(-1/3)² = -(1/3) * -(1/3) = -(1/3) * (1/9) = -1/27

2. Move on to the second term: -(1/2)² = -(1/2) * -(1/2) = -(1/2) * (1/4) = -1/8

3. Now, add the results from the first and second terms: -1/27 - 1/8

4. To combine the fractions, we need to find a common denominator, which is 216 (LCM of 27 and 8): (-1/27) = (-1 * 8)/(27 * 8) = -8/216 (-1/8) = (-1 * 27)/(8 * 27) = -27/216

5. Now, add the fractions together: -8/216 - 27/216 = (-8 - 27)/216 = -35/216

So, the simplified value of the expression is -35/216.
