Answer 1

Răspuns:

m=1

n=0

Explicație pas cu pas:

m)

[(102×14+42×20-1968):100+(13452:38+95×10+2696):1000]:7=

[(1428+840-1968):100+(354+950+2696):1000]:7=

[(2 268-1968):100+(1 304+2696):1000]:7=

(300:100+4000:1000):7=

(3+4):7

7:7=

1

n)

[(121-80:(1596:57+4992:96)-20:(1750:25-3000:60)]-119=

[(121-80:(28+52)-20:(70-50)]-119=

(121-80:80-20:20)-119=

(121-1-1)-119=

(120-1)-119=
