Question

( 2 mũ 2 : 4) . 2 mũ n = 4
 

Answer 1

\(< =>\left(4:4\right).2^n=4< =>2^n=2^2=>n=2\)

Answer 2

\(\left(2^2\div4\right)\times2^n=4\)

\(\left(4\div4\right)\times2^n=4\)

\(1\times2^n=4\)

\(2^n=4\div1\)

\(2^n=4\)

\(2^n=2^2\)

\(n=2\)

Answer 3

( 2² : 4) . 2ⁿ = 4

( 4 : 4 ) . 2ⁿ = 4

         1 . 2ⁿ = 2²

              2ⁿ = 2²

=> n = 2

Answer 4

`(2^2 : 4) . 2^n = 4`

`=> (4 : 4) . 2^n=  4`

`=> 1 . 2^n = 4`

`=>     2^n  = 4`

`=>`    2^n  = 2^2`

`=>        n = 2`

Answer 5

\(\left(2^2:4\right).2^n=4\)

\(\left(4:4\right).2^n=4\)

\(1.2^n=4\)

\(2^n=4:1\)

\(2^n=4\)

\(2^n=2^2\)

\(\Rightarrow n=2\)
