Question

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

Answer 1

\(2^x\cdot1+2^x\cdot2^3=144\)

\(2^x\left(1+8\right)=144\)

\(2^x\cdot9=144\)

\(2^x=144:9\)

\(2^x=16\)

\(2^x=2^4\)

=> x =4 

Answer 2

2^x+2^x+3=144

2^x+2^x.2³=144

2^x.(2³+1)=144

2^x.9=144

2^x=144:9

2^x=16

2^x=2⁴

=>x=4

Answer 3

2^x + 2^x+3  = 144

2^x + 2^x . 2³ = 144

2^x . ( 2³ + 1 ) = 144

2^x . 9 = 144

2^x = 144 : 9

2^x = 16

2^x = 2⁴ 

x = 4
