Question

calcule as potencias b)(2,5³=
c)(1,2³=
​

Answer 1

Resposta:

b) = $\frac{125}{8} = 15,625$

c) = $\frac{216}{125} = 1,728$

Explicação passo-a-passo:

b) 2,5 = $\frac{25}{10}$  -> Simplifique a fraçao por 5

= $\frac{5}{2}$

$(\frac{5}{2} )^{3} = \frac{5^{3} }{2^{3}} = \frac{125}{8} = 15,625$

c) 1,2 = $\frac{12}{10}$ -> Simplifique a fraçao por 2 = $\frac{6}{5}$

$(\frac{6}{5})^{3} = \frac{6^{3} }{5^{3} } = \frac{216}{125} = 1,728$
