​

Answer 1

Resposta:

a)25

b)0

c)1000

d)0.07407...

e)0.04

f) -6

g) 0.01

f)/ 0.0625

Answer 2

A)

${5}^{2} = 5.5 = 25$

B)

${9}^{0} = 1$

C)

${10}^{3} = 10.10.10 = 1000$

D)

$(\frac{2}{3} ) ^{3} = \frac{2.2.2}{3.3.3} = \frac{8}{27}$

E)

$(1.5)^{2} = 1.5 \: . \: 1.5 = 2.25$

F)

$( - 6) ^{ - 1} = \frac{1}{ - 6} = - 0.1666...$

G)

$10 ^{ - 2} = 0.01$

H)

$2 ^{ - 4} = 0.0625$
