Question

5) Resolva:
a) 2-⁵
b) 5-³
c) (1/2)-⁵
d) (2/3)-³​

Answer 1

a)

${2}^{ - 5}$

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

$\frac{1}{32} = 0.03125$

b)

${5}^{ - 3}$

$\frac{1}{ {5}^{3} }$

$\frac{1}{125} = 0.008$

c)

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

${2}^{5} = 32$

d)

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

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

$\frac{ {3}^{3} }{ {2}^{3} }$

$\frac{27}{8} = 3.375$
