Question

Resolva as seguintes potências: ​

Answer 1

C_|

(2/3)^4÷(2/3)^7= (2/3)^4-7= (2/3)^-3=

(2/3)^4÷(2/3)^7=(3/2)^3

(2/3)^4÷(2/3)^7=3^3/2^3=27/8

D_|

(4/9).(4/9).(4/9)=(4/9)^(1+1+1)=(4/9)^3

(4/9)^3= (64/891)

E_|

4^5.4^3/4= 4^(5+3)/4=4^8/4=4^(8-1)=4^7

= 4^7

= 4.4.4.4.4.4.4

=16.384

espero ter ajudado!
