Question

calcule as seguintes potencias
a) (1/3)⁴= b) (-1/5)²= c) (-3/5)³=​

Answer 1

Resposta:

a) $(\frac{1}{3} )^{4} = \frac{1}{3} .\frac{1}{3} .\frac{1}{3} .\frac{1}{3} = \frac{1}{81}$

b) $(-\frac{1}{5} )^{2} = (-\frac{1}{5}) .(-\frac{1}{5}) = \frac{1}{25}$

c)$(-\frac{3}{5} )^{3} = (-\frac{3}{5} ).(-\frac{3}{5} ).(-\frac{3}{5} )= -\frac{27}{125}$
