PAS CU PAS!!!!

Answer 1

Explicație pas cu pas:

3•3•2=9•2=18

(49:7)+86=7+86=93

2•4•9=8•9=72

6•(64:8)=6•8=48

9•(28:4)=9•7=63

(5-2)•(2+2)=3•4=12

4•2•7=8•7=56

6•1•8=6•8=48

(5•5)+(6•6)=25+36=61

(36:4)+39=9+39=48

(3+2)•(9+6)=5•15=75

(9•5)+(6•9)=45+54=99

Answer 2

Răspuns:

3×3×2=9×2=18

(49÷7)+86=7+86=93

2×4×9=8×9=72

6×(64÷8)=6×8=48

9×(28÷4)=9×7=63

(5-2)×(2+2)=3×4=12

4×2×7=8×7=56

6×1×8=6×8=48

(5×5)+(6×6)=25+36=61

(36÷4)+39=9+39=48

(3+2)×(9+6)=5×15=75

(9×5)+(6×9)=45+54=99
