Question

Вычислите по образцу.16*15=(8*5)*(3*2)=;40*6=240,12*15=(6*5)*... вот два образца)а вот надо решить 25*14=,35*18=,18*45=,16*45=,125*12=,65*16=

Answer 1

25*14=(5*2)*(7*5)=350
35*18=(5*9)*(7*2)=630
18*45=(9*6)*(5*3)=810
16*45=(4*5)*(4*9)=720
125*12=(10*3)*(2*25)=1500
65*16=(13*5)*(2*8)=1040

Answer 2

16 * 15 = (8 * 5) * (3 * 2) = 40 * 6 = 240

12 * 15 = (6 * 5) * (2 * 3) = 30 * 6 = 180

25 * 14 = (5 * 5) * (2 * 7) = 25 * 14 = 350

35 * 18 = (7 * 5) * (2 * 9) = 35 * 18 = 630

18 * 45 = (6 * 3) * (9 * 5) = 18 * 45 = 810

16 * 45 = (8 * 2) * (9 * 5) = 16 * 45 = 720

125 * 12 = (25 * 5) * (3 * 4) = 125 * 12 = 1500

65 * 16 = (13 * 5) * (2 * 8) = 65 * 16 = 1040
