89| Calcule as potências. a) ((4)/(9))^2= ((1)/(5))^4= ((7)/(4))^3= d) ((8)/(5))^2= e) ((1)/(3))^0= f) ((1)/(2))^1=

Vamos calcular as potências fornecidas:a) \((\frac{4}{9})^{2}\): b) \((\frac{1}{5})^{4}\): c) \((\frac{7}{4})^{3}\): d) \((\frac{8}{5})^{2}\): e) \((\frac{1}{3})^{0}\): f) \((\frac{1}{2})^{1}\): Portanto, as potências calculadas são:a) \((\frac{4}{9})^{2} = \frac{16}{81}\)b) \((\frac{1}{5})^{4} = \frac{1}{625}\)c) \((\frac{7}{4})^{3} = \frac{343}{64}\)d) \((\frac{8}{5})^{2} = \frac{64}{25}\)e) \((\frac{1}{3})^{0} = 1\)f) \((\frac{1}{2})^{1} = \frac{1}{2}\)
