=> 3x-2^4 = 2.7

=> 3x = 30

=> x = 10

BANG 10 NHE !

( 3x - 2⁴ ) . 7³ = 2.7⁴

=> ( 3x - 16 )  = 2 .( 7⁴ : 7³ )

=> ( 3x - 16 ) = 2 . 7

=> 3x - 16 = 14

=> 3x = 30

=> x = 10

=>(3x-16)=2*7=14

=>3x=30

=>x=10

\(\left(3x-2^4\right).7^3=2.7^4\)

\(\left(3x-2^4\right)=2.7^4\div7^3\)

\(3x-2^4=2.7\)

\(3x-2^4=14\)

\(3x=14+2^4\)

\(3x=30\)

`=>` \(x=30\div3\)

`=> x=10`

\(\left(3x-2^4\right).7^3=2.7^4\)

=> \(\left(3x-2^4\right)=2.7^4:7^3\)

=> \(\left(3x-2^4\right)=2.7^1\)

=> \(\left(3x-2^4\right)=14\)

=> \(3x=14+2^4\)

=> 3x = 14 + 16

     3x = 30

     x=30 : 3

     x = 10

          Vậy x = 10
#Ori_deeptry

/x-3/=7-(-2)

/x-3/=9

x=/9+3/

x=/12/

x=/12/ 

<=> x= 12; -12

( 3x-2⁴)*7³=2*7⁴

(3x-16)*343=4802

3x-16=14

3x=14+16

3x=30

=> x = 10

x-[42+(-28)]=-8

x-14=8

x=8+14

x=22

\(\left(3x-2^4\right).7^3=2.7^4\)

\(\Rightarrow\left(3x-2^4\right)=2.7^4:7^3=14\)

\(\Rightarrow\)\(3x=14+16=30\)

\(\Rightarrow x=30:3=10\)

\(3x-2^4=2.7^4:7^3\)

\(3x-16=2.7\)

\(3x-16=14\)

\(3x=14+16\)

\(3x=30\)

\(x=30:3\)

\(x=10\)

Vậy: x = 10

Nhớ k cho mình nhé! Thank you!!!

3x-2^4 = 2.7^4 : 7^3 = 2.7 = 14

3x = 14 + 2^4 = 14 + 16 = 30

x = 30 : 3 = 10

k mk nha

( 3x - 2⁴ ) . 7³ = 2 . 7⁴

( 3x - 16) . 343 = 4802

3 . x - 16 = 4802 : 343

3 . x - 16 = 14

3 . x = 16 +14

3 . x = 30 

x = 30 : 3 

x = 10 

(3x-2⁴).7³=2.7⁴

(3x-16).343=4802

3x-16=4802:343

3x-16=14

3x=14+16

3x=30

x=30:3

x=10

t ick cho mk nha bn
