5x+x=39-3¹¹:3⁹

6x = 29 - 3²

6x = 29-9

6x =20

x =\(\frac{10}{3}\)

5

\(5x+x=39-3^{11}:3^9.\)

\(5x+x=39-9\)

\(5x+x=30\)

\(\Leftrightarrow x.\left(5+1\right)=30\)

\(x.6=30\)

\(\Rightarrow x=5\)

\(5x+x=39-3^{11}:3^9\)

\(6x=39-3^2\)

\(6x=39-9\)

\(6x=30\)

\(x=30:6\)

\(x=5\)

Vậy \(x=5\)

Tham khảo nhé~

\(5x+x=39-3^{11}:3^9\)

\(5x+x=39-9\)

\(5x+x=30\)

\(\Rightarrow5x+1x=30\)

\(x.\left(5+1\right)=30\)

\(x.6=30\)

\(\Rightarrow x=5\)

Nhớ k nhé !!!! 

^-^

\(5x+x=39-3^{11}:3^9\)

\(x\left(5+1\right)=39-3^2\)

\(6x=39-9\)

\(6x=30\)

\(x=30:6\)

\(x=5\)

Vậy x = 5

Nhớ k cho mình nhé! Thank you!!!

(2x+1).(x-3) lớn hơn hoặc bằng 0,hãy tìm x

thanks nha

5x + x = 39 - 3¹¹ : 3⁹

6x = 39 - 3² = 39 - 9 = 30

x = 30 : 6 = 5

 Bài 1:

1; 5\(x\) + \(x\) = 39 - 3¹¹ : 3⁹

    \(x\).(5 + 1) = 39 - 3²

    \(x.6\)        = 39 - 9

   \(x.6\)         = 30

   \(x\)           = 30 : 6

   \(x\)          = 5

Vậy \(x\) = 5

2; 5\(x\) + \(x\) = 150 : 2 + 3

    \(x\).(5 + 1) = 75 + 3

    \(x.6\)          = 78

    \(x\)             = 78 : 6

     \(x\)            = 13

Vậy \(x=13\) 

3;      7\(x\) - \(x\) = 5²¹ : 5¹⁹ + 3.2² - 1

    \(x.\left(7-1\right)\) = 5² + 6 - 1

    \(x\).6 = 25 + 6 - 1

    \(x.6\) = 31 - 1

   \(x.6\) = 30

   \(x\)    = 30 : 6

    \(x=5\)

Vậy \(x=5\)

\(5x+x=39-3^{11}:3^9\)

\(6x=39-3^2\)

\(6x=30\)

\(x=5\)

\(5x+x=39-3^{11}:3^9\)

\(\Leftrightarrow6x=39-3^2\)

\(\Leftrightarrow6x=39-9\)

\(\Leftrightarrow6x=30\)

\(\Leftrightarrow x=5\left(tm\right)\)

Vậy ..

\(5x+x=39-3^{11}:3^9\)

\(\Leftrightarrow6x=39-3^2\)

\(\Leftrightarrow6x=39-9\)

\(\Leftrightarrow6x=30\)

\(\Leftrightarrow x=5\)

5x + x = 39 - 3^11 : 3^9

  6x     = 39 - 3^2

  6x     = 39 - 9

  6x     = 30

    x     = 30 : 6

    x     = 5

5x + x = 39 - 3¹¹ : 3 ⁹

6x       = 39 - 3 ^{11 - 9}

6x       = 39 - 3 ²

6x       = 39 - 9

6x        = 30

x          = 5

đề thế này phải ko?

5x + x + 39 = 3¹¹ : 3⁹

5x + x + 39 = 3^11-9

5x + 1x + 39 = 3²

(5+1)x + 39 = 9

6x = 9 + 39

6x = 48

x = 48 : 6

x  = 8

đúng ko?
