55 x 45 + 55 x 55
= 55 x ( 45 + 55 )
= 55 x 100
= 5500

(26 x 27 + 26 x 73) x (30 x 31 - 30) x (34 x 110 - 55 x 68) x (55 x 68 + 55 x 32)
= [26 x (27 + 73)] x [30 x (31 - 1) x (34 x 55 x 2 - 55 x 68) x [55 x (68 + 32)
= (26 x 100) x (30 x 30) x [68 x 55 - 55 x 68) x (55 x 100)
= 2600 x 900 x (68 x (55 - 55) x 5500
= 2600 x 900 x (68 x 0) x 5500
= 2600 x 900 x 0 x 5500
= 0
vì 0 nhân với số nào cũng bằng 0

x+45=45-45+55:55
x+45=0+1
x+45=1
x=1-45
x=-44
k nhé mk vừa k bn rùi
x + 45 = 45 - 45 + 55 : 55
x + 45 = 45 - 45 + 1
x + 45 = 0 + 1
x + 45 = 1
x = 1 - 45
x = -44
