Vậy x=23
@hoang de thang
đương nhiên phải dài phải hay mới xứng tay với chụy
12x-33=3^2.3^3
12x-33 = 3^2.3^3
=> 12x-33 = 3^5
=> 12x-33 = 243
=>12x = 243+33
=>12x = 276
=> x = 276:12
=> x = 23
\(12x-33=3^2.3^3=3^{2+3}=3^5\)
\(\Leftrightarrow12x=3^5+33=3.3^4+3.11=3\left(3^4+11\right)\)
\(\Leftrightarrow12x=3\left(81+11\right)=3.92\)
\(\Leftrightarrow x=\frac{92.3}{12}=\frac{23.4.3}{3.4}=23\)
Vậy \(x=23\)

Nhấn đúng cho mk nha!!!!!!!!
ồ
dễ nhỉ
thế cũng hỏi sao
k mk nha
k mk mk k lại
5(x+35)=515
12x-33=3^2.3^3
\(5\left(x+35\right)=515\)
\(\Rightarrow5x+5.35=515\)
\(\Rightarrow5x+175=515\)
\(\Rightarrow5x=340\)
\(\Rightarrow x=68\)
\(12x-33=3^2.3^3\)
\(\Rightarrow12x-33=3^5\)
\(\Rightarrow12x-33=243\)
\(\Rightarrow12x=276\)
\(\Rightarrow x=276:12\)
\(\Rightarrow x=23\)
5.(x + 35 ) = 515
= ( x + 35 ) = 515 : 5
= x + 35 = 103
= x = 103 - 35
=x = 68

giúp mình nhé!
a) 96 - 3 (x - 1) = 42
3 (x - 1) = 96 - 42
