Question

помогите дам 100 пажалуста на тетради и фото​

Answer 1

Пошаговое объяснение:

№1

1) - (1/3)² = - (1/3 * 1/3) = - 1/9

2) (1/2)² = 1/2 * 1/2 = 1/4

3) -1/9 - 1/4 = -4/36 - 9/36 = -13/36

4) -13/36 + 1 = -13/36 + 36/36 = 23/36

№2

1) (1/2)³ = 1/2 * 1/2 * 1/2 = 1/8

2) (1/4)² = 1/4 * 1/4 = 1/16

3) 1/8 + 1/16 = 2/16 + 1/16 = 3/16

4) 3/16 - 1 = 3/16 - 16/16 = -13/16

Answer 2

Ответ:

$1) - ( \frac{1}{3} {)}^{2} - ( \frac{1}{2} {)}^{2} + 1$

$- \frac{1}{9} - \frac{1}{4} + 1$

$\frac{23}{36}$

$2)( \frac{1}{2} {)}^{3} + ( \frac{1}{4} {)}^{2} - 1$

$\frac{1}{8} + \frac{1}{16} - 1$

$- \frac{13}{16}$
