(3x + 10)3 . 46 = 49
\(\Rightarrow\)(3x + 10)3 = 49 : 46 = 43
\(\Rightarrow\)3x + 10 = 4
\(\Rightarrow\)3x = -6
\(\Rightarrow\)x = -2
(3x+10)3.46=49
[(3x)3+3.(3x)2.10+3.3x.102+103 )].4096 = 262144
[27x3+270x2+900x+1000] .4096 = 262144
27x3+270x2+900x+1000.4096 = 262144
110592x3+1105920x2+3686400x+4096000 = 262144
110592x3+1105920x2+3686400x = 262144+4096000
110592x3+1105920x2+3686400x = 4358144
Phần còn lại tự làm nha
Mik bận rùi ^^
Bài làm hơi dài tý
