Question

Me ajudem nesse dever de matemática ​

Answer 1

Explicação passo-a-passo:

a)

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

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

$\frac{9}{4}$

b)

${( + \frac{5}{ {4}^{2} } )}^{2}$

${( \frac{5}{16} )}^{2}$

$\frac{25}{256}$

c)

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

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

$- \frac{ {1}^{5} }{ {2}^{5} }$

$- \frac{1}{32}$

d)

${( - \frac{15}{ {3}^{3} } )}^{0}$

$1$

e)

${( - \frac{3}{5} )}^{3}$

$- {( \frac{3}{5}) }^{ 3}$

$- \frac{ {3}^{3} }{ {5}^{3} }$

$- \frac{27}{125}$

f)

$(7) ^{3}$

$7 \times 7 \times 7$

$343$

g)

${( - 6)}^{3}$

${ - 6}^{3}$

$- (6 \times 6 \times 6)$

$- 216$

h)

${( - 3)}^{3}$

${ - 3}^{3}$

$- (3 \times 3 \times 3)$

$- 27$
