Establezca si cada una de las siguientes igualdades es válida o no.
2.6=2.6=12=4
4.5 =4.5=45 =15

3.8.4=3.8=24.4=96 =48=24
4 .5.4=4.5=20.5=180=90=45

(8).(15)=8.15=120=60=30
(3).(4) =3.4 =12=6=3

2.5.10=2.3=6.10 =60=30=15 =2
5.6.7 =6.5=30 =210=105=35 =7

(18) / (8) = (13).(33)=594=297
(11)/ (33)= (11).(8) =88= 44

(14)/ (6) = (14).(15)=210=105
(3) / (15) =(3).(6) =18 = 9

4 / (2).8)= 4. (2.8)= 16
9 / (3)= 9.(3.1) =3
4/ 3 = 12 =6= 3
9/10 =144=72=36


(12).15) / 20 =12.15=180/ 20=180=7
