(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
\(\Leftrightarrow3x-16=2.7^4+7^3=5145\Leftrightarrow3x=5161\Leftrightarrow x=\dfrac{5161}{3}\)
\(\left(3x-2^4\right)-7^3=2.7^4\\ \Leftrightarrow\left(3x-16\right)=2.7^4+7^3\\ \Leftrightarrow3x-16=5145\\ \Leftrightarrow3x=5145+16=5161\\ \Leftrightarrow x=\dfrac{5161}{3}\)
( 3x - 24 ) . 73 = 2. 74
3x - 16 = 2 . ( 74 : 73 )
3x - 16= 2 . 71
3x - 16 = 14
3x = 14 + 16
3x = 30
x = 30 : 3
x = 10
(3x-24).73=2.74
3x-24=2.74:73
3x-24=2.(74:73)
3x-24=2.7
3x-16=14
3x=14+16
3x=30
x=30:3
x=10
Vậy x=10
\(\left(3x-2^4\right).7^3=2.7^4\\ \Leftrightarrow3x-16=2.7^4:7^3\\ \Leftrightarrow3x=14+16\\ \Leftrightarrow3x=30\\ \Leftrightarrow x=10\)
Vậy...
\(\left(2x-2^4\right).7^3=2.7^4\)
\(\Leftrightarrow\left(2x-2^4\right)=2.7^4:7^3\)
\(\Leftrightarrow2x-2^4=2.7\)
\(\Leftrightarrow2x-16=14\)
\(\Leftrightarrow2x=30\)
\(\Leftrightarrow x=15\)
Vậy ..
\(\left(3x-2^4\right).7^3=2.7^4\)
=> \(\left(3x-2^4\right)=2.7^4:7^3\)
=> \(\left(3x-2^4\right)=2.7^1\)
=> \(\left(3x-2^4\right)=14\)
=> \(3x=14+2^4\)
=> 3x = 14 + 16
3x = 30
x=30 : 3
x = 10
Vậy x = 10
#Ori_deeptry
=>(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`
