x : 7 = x : 6 vay x la

Bieu thuc y = f(x) = B = /\(B=1/(√x +2016 ) \)

neu y = 3 vay x =

neu a thuoc z thi x=y vay ai tra loi dc cau hoi nay

9 - x tren 13-x =1 phan 2 vay x = ... ; 7+y tren 15+y = 1 phan 2 vay x = ...

Neu 9=63

8=48

7=35

6=24

Vay 4=?

x-(-25-17-2x)6+x vay x = ?

tim x biet 

x+12345=132564

ban nao tra oi dau tien minh se tick va ban ay phai nho ket ban voi minh nhe

neu ban do het luot ket ban roi thi ba thu hai ket neu ban thu hai cun vay thi se tiep tuc

x-(-25-17-2.x)=6+x vay x=?

(6.x-3^4).7^3=7^4

nho neu cach giai nua nha
