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

\(5x+x=39-3^2\)\(5x+x=39-9=30\)

\(6x=30\)

\(x=30:6=5\)

Chúc bn hok tốt ....

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

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

\(5x+x=30\)

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

\(x.6=30\)

\(\Rightarrow x=5\)

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

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

\(6x=39-9\)

\(6x=30\)

\(x=30:6\)

\(x=5\)

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

Vậy ..

\(\Leftrightarrow6x=30\)

\(\Leftrightarrow x=5\)

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?
