Tìm x biết : 

\(^{2^{50}\div2^x-5=11}\)

Answer 1

\(2^{50}:2^x-5=11\)

\(2^{50-x}=11+5=16\)

\(2^{50-x}=2^4\)

\(50-x=4\)

\(x=50-4\)

\(x=46\)

Answer 2

\(2^{50}\div2^x-5=11\)

\(\Rightarrow2^{50}\div2^x=16\)

\(\Rightarrow2^{50}\div2^x=2^4\)

\(\Rightarrow2^x=2^{46}\)

\(\Rightarrow x=46\)

Answer 3

2⁵⁰ : 2^x -5=11

2⁵⁰ : 2^x =11+5

2⁵⁰ : 2^x =16

2⁵⁰ : 2^x = 2⁴                        2 mũ 4 bằng 16 nha bạn

x=50-4=46

Answer 4

\(2^{50}\div2^x-5=11\)

\(2^{50}\div2^x=11+5\)

\(2^{50-x}=16\)

\(2^{50-x}=2^4\)

\(\Rightarrow50-x=4\)

\(\Rightarrow x=50-4\)

\(\Rightarrow x=46\)

Answer 5

\(2^{50}:2^x-5=11\)

\(2^{50-x}=11+5\)

\(2^{50-x}=16\)

\(2^{50-x}=2^4\)

Vì \(2=2\)

\(\Rightarrow50-x=4\)

\(x=50-4\)

\(x=46\)
