Question

49- De maneira semelhante resolva

a) (4/3×5/16+7/4)^2

Answer 1

( 4/3  *  5/16 +  7/4 )² 

4/3 *  5/16 = 20/48  = 5/12 ***
( 5/12 + 7/4 )²
mmc 12 e 4 = 12
[ ( 5 + 21 )/12 ]²  =
( 26/12)²  = 26/12 * 26/12 = 676/144  =169/36 = 4 inteiros  25/36
( 169 : 36 = 4 e resta 25 )
 

Answer 2

Resposta:

( 4/3 * 5/16 + 7/4 )²

4/3 * 5/16 = 20/48 = 5/12 ***

( 5/12 + 7/4 )²

mmc 12 e 4 = 12

[ ( 5 + 21 )/12 ]² =

( 26/12)² = 26/12 * 26/12 = 676/144 =169/36 = 4 inteiros 25/36

( 169 : 36 = 4 e resta 25 )
