Question

2 mũ x cộng 1 - 2 mũ x bằng 32

Answer 1

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

\(\Leftrightarrow2^x.2-2^x=2^5\)

\(\Leftrightarrow2^x.\left(2-1\right)=2^5\)

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

\(\Leftrightarrow x=5\)

Vậy : \(x=5\)

Answer 2

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

\(\Leftrightarrow2^x.2-2^x=2^5\)

\(\Leftrightarrow2^x.\left(2-1\right)=2^5\)

\(\Leftrightarrow2^x=2^5\)

\(\Rightarrow x=5\)

Answer 3

2^x+1 -2^x =32

2^x.2 - 2^x .1 =2⁵

2^x . (2 -1) =2⁵

2^x . 1 =2⁵

^{Vay x =5}

Answer 4

x = 5
