Answer 2

\(4^{x+1}=1024\)

\(\Rightarrow4^x.4=1024\)

\(\Rightarrow4^x=\dfrac{1024}{4}=256\)

\(\Rightarrow4^x=4^4\)

\(\Rightarrow x=4\)

Answer 3

`4^(x+1) = 1024`

`=>4^(x+1) = 4^5`

`=> x+ 1 = 5`

`=> x        = 5 - 1`

`=> x        = 4`

Answer 4

Answer 5

4^x+1 = 1024
4^x+1 = 4⁵

=> x + 1 = 5
           x = 5 - 1
           x = 4
Vậy x = 4
