Question

\(2^{4-2x}=16^4\)

Answer 1

\(2^{4-2x}=\left(2^4\right)^4\\ 2^{4-2x}=2^{16}\\ 4-2x=16\\ -2x=16-4\\ -2x=12\\ x=12:\left(-2\right)\\ x=-6\)

Answer 2

\(2^{4-2x}=16^4\)

\(2^{4-2x}=2^{16}\)

`4-2x=16`

`2x=4-16`

`2x=-12`

`x=-12:2`

`x=-6`

Vậy `x=-6`

Answer 3

\(2^{4-2x}=16^4\)

\(2^{4-2x}=2^{16}\)

\(\Rightarrow4-2x=16\)

           \(2x=4-16\)

           \(2x=-12\)

             \(x=-12:2\)

             \(x=-6\)
