vì khi gấp 1 số hạng bất kì thì chúng đều có ảnh hưởng đến nhau nên ta chỉ việc lấy 3 x  2 = 6 thôi anh chắc chắn 100% luôn

Ta coi thua so thu nhat la : A 

          thua so thu hai la : B 

Ta co :

A x B  = 1265 

Suy ra : a = 2 ; b = 3 = 6 

Vay h moi la :  6 x 1265 = 7590

                                       Dap so : 7590

k nha 

vì chúng đều có ảnh hưởng đến nhau nên ta chỉ việc lấy 3x2 =6

song rồi chỉ việc lấy 1265 x 6 = 7590    xin lổi vì câu kia mình quên nhân lên

Goi thua so thu nhat la: a

Goi thua so thu hai la : b

theo bai ra ta co:

a x b = 1265

a x 2 x b x 3 = 1265 x( 2 x 3)

a x 2 x b x 3 = 1265 x 6

a x 2 x b x 3 = 7590

Vay h moi la : 7590

Goi thua so thu nhat la : a

Goi thua so thu hai la : b 

Theo bai ra, ta co :

a x b = 1265

a x 2 x b x 3 = 1265 x ( 2 x 3 )

a x 2 x b x 3 = 1265 x 6

a x 2 x b x 3 = 7590

Vay h moi la : 7590

Lấy 2 nhân 3 bằng 6 roi 1265 nhân 6 =7590

Gọi thừa số thứ nhất là A

Gọi thừa số thứ hai là B

Theo bài ra ta có:

AxB=1265

Ax2xBx3=1265x(2x3)

Ax2xBx3=1265x6

Ax2xBx3=7590

     vậy tích mới là7590

trrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
