cứu

Answer 1

\(2^{x+1}-2^x=32\)

\(\Leftrightarrow2^x.\left(2-1\right)=32\)

\(\Leftrightarrow2^x.1=32=2^5\)

\(\Leftrightarrow x=5\)

Vậy x = 5

Answer 2

x=5

Answer 3

2^x+1-2^x=32

\(\Rightarrow\)(2^x).2-(2^x).1=32

(2^x).(2-1)=32

\(\Rightarrow\)2^x=32

2^x=2^5

\(\Rightarrow\)x=5\(\in\)N.

Vậy x=5.
