@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 \(x=23\)

\(5\left(x+35\right)=515\)
\(\Rightarrow5x+5.35=515\)
\(\Rightarrow5x+175=515\)
\(\Rightarrow5x=340\)
\(\Rightarrow x=68\)
\(12x-33=3^2.3^3\)

5.(x + 35 ) = 515
= ( x + 35 ) = 515 : 5
= x + 35 = 103
= x = 103 - 35

96-3(x+1)=42
12x-33=3^2.3^3
giúp mình nhé!
a) 96 - 3 (x - 1) = 42
3 (x - 1) = 96 - 42
3 (x -1) = 54
x - 1 = 54 : 3
x - 1 = 18
x = 18 + 1
x = 19
b) 12x - 33 = 32 . 33
12x - 33 = 35
12x - 33 = 243
12x = 243 + 33
12x = 276
x = 276 : 12
x = 23
Bạn nhớ kiểm tra lại nha dinh nguyen
96 - 3( x+ 1 ) = 42
3( x + 1 ) = 96 - 42
3( x + 1 ) = 54
x + 1 = 54 : 3
x + 1 = 18
x = 18 - 1
x = 17
12x - 33 = 3 ^ 2 . 3 ^ 3
12x - 33 = 9 . 27
12x - 33 = 243
12x = 243 + 33
12x = 276
x = 276 : 12
x = 23
Tim x số tự nhiên biết
12x - 33 = 3^2.3^3
a, 12x- 33 = 3^2.3^3 b,96-3(x+1)=42
các bn ơi giúp mik giải bài này với mik vội lắm mai mik nộp rồi
12x-33=3 mũ 2.3 mũ 3
12x-33=32.33
12x =243
x =243:12
x =20,25
k
a 5(x+35)=515
b 12x-33=3^2.3^3
c 541+(218-x)=73
d 1230:3(x-20)=10
a) 5(x + 35) = 515
x + 35 = 515 : 5
x + 35 = 103
x = 103 - 35
x = 68
b) 12x - 33 = 32.33
12x - 33 = 35
12x - 33 = 243
12x = 243 + 33
12x = 276
x = 276 : 12
x = 23
c) 541 + (218 - x) = 73
218 - x = 73 - 541
218 - x = -468
-x = -468 - 218
-x = -686
x = 686
d) 1230 : 3(x - 20) = 10
410(x - 20) = 10
x - 20 = 10 : 410
x - 20 = 1/41
x = 1/41 + 20
x = 821/41
5(x+ 35 ) = 515
x + 35 = 103
x = 68
12x - 33 = 32 . 33
12x = 276
x = 23
541 + ( 218 - x ) = 73
218 - x = - 468
x = - 250
1230 : 3( x - 20 ) = 10
=> 3x - 60 = 123
=> 3x = 183
=> x = 61
Study well
a) \(5\left(x+35\right)=515\)
\(\left(x+35\right)=515:5\)
\(x+35=103\)
\(x=103-35\)
\(x=68\)
Vậy \(x=68\)
b) \(12x.-33=3^2.3^3\)
\(12x.-33=9.27\)
\(12x.-33=243\)
\(12.x=243+33\)
\(12.x=276\)
\(x=276:12\)
\(x=23\)
Vậy \(x=23\)
c) \(541+\left(218-x\right)=73\)
\(\left(218-x\right)=73-541\)
\(218-x=-468\)
\(x=218-\left(-468\right)\)
\(x=218+468\)
\(x=686\)
Vậy \(x=686\)
d) \(1230:3\left(x-20\right)=10\)
\(3.\left(x-20\right)=1230:10\)
\(3.\left(x-20\right)=123\)
\(\left(x-20\right)=123:3\)
\(x-20=41\)
\(x=41+20\)
\(x=61\)
Vậy \(x=61\)
Chúc bạn học tốt !!!
