Question

pvfff me ajudemmm e pra hjjj responder so a 33​

Answer 1

a)   $3^{7} :3^{5} = 3^{7-5} = 3^{2} = 9$  

b) $(-1)^{8} : (-1)^{6} =(-1)^{8-6} = (-1)^{2} = +1$    

c) $(\frac{2}{3} )^{6} :(\frac{2}{3} )^{1}= (\frac{2}{3} )^{6-1}= (\frac{2}{3} )^{5}= (\frac{2^{5} }{3^{5} } )= \frac{32}{243}$

d)                                    

$2^{10} = 1024\\\\1024 : 2 = 512$    

 e) $(-2,5)^{5} : (-2,5)^{2} = (-2,5)^{5-2}= (-2,5)^{3}= - 15,625$

f) $a^{9} : a^{8}= a^{9-8}= a^{1}= a$  

g)  $1^{8}:1^{2} = ^{8-2}= 1^{6}= 1$

H) não consegui ler
