av rog mult dau coroana! =(

Answer 1

A) 2x8x5 = 2 x 5 x 8 = 10 x 8 = 80 

b) 12x5x20 = 12 x 100 = 1200

;c)5x125x18x2x8 = 125 x 8 x 5 x 2 x 18 = 1000 x 10 x 18 = 18000

d)125x37x8 = 125 x 8 x 37 = 1000 x 37 = 37000

e) 12x54+46x12  = 12 ( 54 + 46) = 12 x 100 = 1200

f) 147x(874-74) = 147 x 800 = 117600

g)(567-17)x(47+13) = 550 x 60 = 33000
