Answer 4

3 x 2ⁿ=48

=>2ⁿ= 48:3

=>2ⁿ=16

Mà: 2⁴=16

=> 2ⁿ=2⁴=16

=>n=4

Answer 5

\(3\cdot2^n=48\)

\(2^n=48:3\)

\(2^n=16\)

\(2^n=2^4\)

\(=>n=4\)

Answer 6

   3 x \(2^n\) = 48

=>   \(2^n\)= 48  : 3

=> \(2^n\) =  16

mà \(2^n\) =  \(2^4\)

=> n = 4                                                                                                                                                                                        

Answer 7

3x2ⁿ=48

2ⁿ=48/3

2ⁿ=16

2ⁿ=2⁴

=>n=4
