vay x=105
nhớ **** cho mình nha
tìm số tự nhiên x, biết:
a/ 2x-138=2^3.3^2

giai day du nha may ban
2x-2 mũ 3.3 mũ 2=138
tìm x
A: 2x-5=9
B:5x-138=\(2^3.3^2\)
Tìm x biết 2.x-138=\(2^3.3^2\)
tim x
a,2x-138=2^3.3^2
b,20-[7.(x-3)+4]=2
c,[6x-39]*3.28=5628
tìm x tự nhiên x ,biết:
a) 2.x-138=2^3.3^2
b) 231-(x-6)=1339:13
2.x -138=2^3.3^2
2.x-138=2^3.3^2
