131 . x - 941 = 27 . 23
131 . x - 941 = 27+3
131 . x - 941 = 210
131 . x - 941 = 1024
131 . x = 1024 + 941
131 . x = 1965
x = 1965 : 131
x = 15
Vậy x = 15
nhé
thien binh cong chua
k mình nhé bạn mình trả lời đầu tiên !
\(\Rightarrow131.x-941=1024\)
\(\Rightarrow131x=1965\)
\(\Rightarrow x=15\)
131 . x - 941 = 2^7 . 2^3
131 . x - 941 = 2^10
131 . x - 941 = 1024
131 . x = 1024 + 941
131 . x = 1965
x = 1965 : 131
x = 15
\(131.x-941=2^7.2^3\)
\(131x-941=2^{10}\)
\(131.x-941=100\)
\(131.x=100+941\)
\(131.x=1041\)
\(x=1041:131\)
\(x=\)........
131.x - 941 = 2^10
131.x =2^10+941
131.x =1024+941
131.x =1965
x =1965:131
x =15
