Упростите выражение: 2a*7*5b = 15*c*4*3d = 7m*8*5n = 8x*3y*125 = 5m*6*20n = 4a*9*25b = 5a*9*4b = 12c*2*3d = 125m*7*8n

2a*7*5b = (2*7*5) * (a*b) = 70*ab = 70ab

15*c*4*3d = (15*4*3) * (c*d) = 180 * cd = 180cd

7m*8*5n = (7*8*5) * (m*n) = 280 * mn = 280mn

8x*3y*125 = (125 * 8 * 3) * (x * y) = 3000 * xy = 3000xy

5m*6*20n = (5*6*20) * (m*n) = 600 * mn = 600mn

4a*9*25b = (4*9*25) * (a*b) = 900 * AB = 900ab

5a*9*4b = (5*9*4) * (a*b) = 180 * AB = 180ab

12c*2*3d = (12*2*3) * (c * d) = 72 * cd = 72cd

125m*7*8n = (125*7*8) * (m*n) = 7000 * mn = 7000mn
