Question

calcule as potências,com as contas montadas

${4}^{ - 2}$
${4}^{ - 3}$
${5}^{ - 1}$
${3}^{ - 3}$
${10}^{ - 2}$
​

Answer 1

Resposta:

1/16

1/64

1/5

1/27

1/100

Explicação passo a passo:

Expoente negativo inverte e deixa a potência positiva

$(\frac{4}{1}) ^{-2} = (\frac{1}{4} )^{2} = \frac{1}{16}$

$( \frac{1}{4} )^{3} = \frac{1}{64}$

1/5

1/27

1/100

Answer 2

Resposta:

$4 {}^{ - 2}$

$\frac{1}{4 {}^{2} }$

$\frac{1}{16}$

~~~~~~~~~~~~~~~~~~~\\~~~~~~~~~~~~~~~~\\~~~~~~~~~

$4 {}^{ - 3}$

$\frac{1}{4 {}^{3} }$

$\frac{1}{64}$

~~~~~~~~~~~~~~~~~\\~~~~~~~~~~~~~~~~\\~~~~~~~~~~~

$5 {}^{ - 1}$

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

$\frac{1}{5}$

~~~~~~~~~~~~~~~~\\~~~~~~~~~~~~~~~~\\~~~~~~~~~~~~

$3 {}^{ - 3}$

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

$\frac{1}{27}$

~~~~~~~~~~~~~~~~~\\~~~~~~~~~~~~~~~\\~~~~~~~~~~~~

$10^{ - 2}$

$\frac{1}{10 ^{2} }$

$\frac{1}{100}$
