Question

2^x+3+2^x=144

Answer 1

2^{x + 3} + 2^x = 144

2^x.2³ + 2^x = 144

2^x.(2³ + 1) = 144

2^x.9 = 2⁴.9

x = 4

Answer 2

x=4 nhé 

k dùm mình nha

Answer 3

x bang 4 do

Answer 4

2^x+3 + 2^x = 144

2^x . 2³ + 2^x . 1 = 144

2^x . ( 2³ + 1 ) = 144

2^x . 9 = 144

2^x = 144 : 9

2^x = 16

2^x = 2⁴

=> x = 4

Answer 5

\(2^{x+3}+2^x=144\)

\(2^x.2^3+2^x=144\)

\(2^x.2^3+2^x.1=144\)

\(2^x.\left(2^3+1\right)=144\)

\(2^x.9\)             \(=144\)

\(2^x\)                 \(=144:9\)

\(2^x\)                   \(=16\)

\(2^x\)                    \(=2^4\)

\(=>x=4\)
