Question

1 Calcule as potências seu caderno:
A)(2/7)^0
B)(2/7)^1
C)(0,3)^2
D)(-3/5)^2
E)(-3/5)^3
F)(-2,1)^2
G)(-0,4)^3
H)(3,2)^2

Answer 1

Resposta: Estudar as propriedades de Potência

Explicação passo-a-passo:

$[tex]a)(\frac{2}{7})^0 =1\\\\b)(\frac{2}{7})^1=\frac{2}{7}\\\\c) (\frac{3}{10})^2=\frac{3^2}{10^2}=\frac{9}{100}\\\\\d) (\frac{-3}{5})^2=\frac{(-3)*(-3)}{5*5}=\frac{9}{25}\\\\e)(\frac{-3}{5})^3=\frac{(-3)*(-3)*(-3)}{5*5*5}=\frac{-27}{125}\\\\\f) (\frac{-21}{10})^2=\frac{(-21)*(-21)}{10*10}=\frac{441}{100}\\\\g)(\frac{-4}{10})^2=\frac{(-4)*(-4)}{10*10}=\frac{16}{100}\\\\\h) (\frac{32}{10})^2=\frac{32*32}{10*10}=\frac{1024}{100}$
