x-1-2-3-4=0
=> x-(1+2+3+4)=0
x-10=0
x=10
k mik nha
x - 1 - 2 - 3 - 4 = 0
x - ( 1 + 2 + 3 + 4 ) = 0
x - 10 = 0
x = 10
x - 1 – 2 – 3 – 4 = 0
x -1-2-3-4=0
tìm x
x- 1 -2 -3 - 4 = 0
Tính nhẩm :
1 x 2 x 3 x 4 x 5 x 0 = ............
\(x-1-2-3-4=0\sqrt{\sqrt[]{}\dfrac{ }{ }}\)
Tính nhẩm
a) 6 x 2 = ..... 6 x 3 = ..... 6 x 8 = ..... 6 x 1 = .....
6 x 4 = ..... 6 x 5 = ..... 6 x 9 = ..... 1 x 6 = .....
6 x 6 = ..... 6 x 7 = ..... 6 x 10 = ..... 0 x 6 = .....
b) 6 x 5 = ..... 6 x 4 = ..... 3 x 6 = ..... 2 x 6 = .....

Tìm x
a) x - 452 = 77 + 48
b) x + 58 = 64 + 58
c) x - 1 - 2 - 3 - 4 = 0
Tính
4 x 4 + 29 =………………… 20 : 4 x 3 =…………………
3 : 3 x 0 = ………………. 25 : 5 x 1 =……………………
