Trả lời
x:(1/2+1/3+1/6)=2019
x:6/6 =2019
x:1 =2019
=>x =2019.1
=>x =2019
Học tốt !
x : (\(\frac{1}{2}\)+ \(\frac{1}{3}\)+ \(\frac{1}{6}\)) = 2019
x : 1 = 2019
x = 2019
x : ( 1/2 + 1/3 + 1/6 ) = 2019
x : ( 3/6 + 2/6 + 1/6 ) = 2019
x : 1 = 2019
x = 2019 . 1
x = 2019
x:(\(\frac{1}{2}\)+\(\frac{1}{3}\)+\(\frac{1}{6}\))=2019
x:1=2019
x= 2019:1
x=2019
x : ( 1/2 + 1/3 + 1/6 ) = 2019
x : ( 3/6 + 2/6 + 1/6 ) = 2019
x : 1 = 2019
x = 2019 . 1
x = 2019
Đến sáng thì lo gì: :)))))))
Ko ghi lại đề
=> x : (3/6 +2/6 +1/6) =2019
x:1=2019
x=2019 x 1
x=2019
