Question

escreva na forma de potência com expoente negativo: a)(1\10)com o 10 elevado a 2 b)1\16 c)(-1\25) d)1\25 e)1\15 f)(-1\100) g)8\125 h)81\16 i)(-49\36 me ajudem porfavor

Answer 1

a) $\frac{1}{10^2} = 10^-2$

b) $\frac{1}{16} = 16^{-1} = 4^{-2}$

c)$- \frac{1}{25} = -25^{-1} =-5^{-2}$

d)$\frac{1}{25} = 25^{-1}=5^{-2}$

e)$\frac{1}{15} = 15^{-1}$

f)$- \frac{1}{100} =-100^{-1} =- 10^{-2}$

g)$\frac{8}{125} = (\frac{5}{2})^-3$

h)$\frac{81}{16} = (\frac{4}{9})^{-2}$

i)$- \frac{49}{36} = - (\frac{6}{7})^{-2}$
