Question

rezolva ca in exemplu:
model:(8*3)+(8*2)=8*(3+2)=8*5=40
 (5*3)+(5*2)=
(8*5)+(8*4)=
(6*7)+(2*7)=
(2*9)-(2*4)=
(4*7)-(4*5)=
(8*%)-(3*5)=

Answer 1

=5*(3+2)=5*5=25
=8*(5+4)=8*9=72
=7*(6+2)=7*8=56
=2*(9-4)=2*5=10
=4*(7-5)=4*2=8
=5*(8-5)=5*3=15

Answer 2

(5*3)+(5*2)=5*(3+2)=5*5=25
(8*5)+(8*4)=8*(5+4)=8*9=72
(6*7)+(2*7)=7*(6+2)=7*8=56
(2*9)-(2*4)=2*(9-4)=2*5=10
(4*7)-(4*5)=4*(7-5)=4*2=8
(8*5)-(3*5)=5*(8-3)=5*5=25
