Question

{126-4x[3600:60-7x(54:9)+3]}:7+3=27:3

Answer 1

Răspuns:

Explicație pas cu pas:

{126 - 4 x [ 3 600 : 60 - 7 x ( 54 : 9 ) + 3 ] } : 7 + 3 = 27 : 3 ( ADEVARAT)

[ 126 - 4 x ( 60 - 7 x 6 + 3 )] : 7 + 3 = 9 √

= [ 126 - 4 x ( 60 - 42 + 3 ) ] : 7 + 3 =

= [ 126 - 4 x ( 18 + 3 ) ] : 7 + 3 =

= ( 126 - 4 x 21 ) : 7 + 3 =

= ( 126 - 84 ) : 7 + 3 =

= 42 : 7 + 3 =

= 6 + 3 =

= 9
