Question

Quanto é (2/3)^-2 * (2/3)^4+ [(1/3)^2]^3 : 3^-4 ?

Answer 1

(3/2)^2 . (2/3)^4 +[(1/9)]^3 : (1/3)^4∴ 9/4 . 16/81+ [1/729]:1/81∴ 4/9 + 1/729.81/1 ∴ 4/9 + 1/9 = 5/9

Answer 2

Quanto é (2/3)^-2 * (2/3)^4+ [(1/3)^2]^3 : 3^-4 ?(3/2)^2 *(2/3)^4 + [ 1/9 ]^3 :  (1/3)^4

9  *  16 +    1    :   1
4     243    243     81

1 * 4 +  1    *  81
1  27   243      1
  
 4   +   1 ==>   4+9 
27       3            27
