Question

Plasati parantezele patrate rotunde astfel incat sa obtineti o propozitie adevarata:a)24÷(-4)-68+(-4)a puterea3)-20=-30
b)16×(-2)la puterea3)-44-78-30=-124

Answer 1

a ) 24 : ( -4 ) - 68 + ( -4 ) la puterea a 3 - 20 = -30
[ 24 : ( -4 ) ] - [ 68 + ( -54 ) ] - 20 = -30
-6 -4 - 20 = -30

b ) 16 x ( -2 ) la puterea a 3 - 44 - 78 - 30 = -124
[ 16 x ( -8 ) ] - [ 44 - ( 78 - 30 ) ] = -124
-128 - ( 44 - 48 ) = -124
-124 + 4 = -124
