Answer 1

( 5 - 1/2 )² : ( 1/2 - 2)³

(10/2 - 1/2)² : (1/2 - 4/2)³

(9/2)² : (-3/2)³

81/4 : -27/8

81/4 × -8/27

81/27 × -8/4

3 × -2

-6 ✓

Answer 2

Resposta:

$(5 - \frac{1}{2} ) {}^{2} \div ( \frac{1}{2} - 2) {}^{3}$

$( \frac{9}{2} ) {}^{2} \div ( - \frac{3}{2} ) {}^{3}$

$( \frac{9}{2} ) {}^{2} \div ( - ( \frac{3}{2} ) {}^{3} )$

$- ( \frac{9}{2} ) {}^{2} \div ( \frac{3}{2} ) {}^{3}$

$- \frac{81}{4} + \frac{27}{8}$

$- \frac{81}{4} \times \frac{8}{27}$

$- \frac{3}{4} \times 8$

$- 3 \times 2$

$- 6$
