Bài toán2^x+2^4:4^2=33

2 câu trả lời

` 2^x + 2^4 : 4^2 = 33 `

` 2^x + 2^4 : ( 2^2 )^2 = 33 `

` 2^x + 2^4 : 2^[2.2] = 33 `

` 2^x + 2^4 : 2^4 = 33 `

` 2^x + 1 = 33 `

` 2^x = 33 - 1 `

` 2^x = 32 `

` 2^x = 2^5 `

` ⇒ x = 5 `

 Vậy ` x = 5 ` 

`2^x + 2^4 : 4^2 = 33`

`=> 2^x + 16 : 16 = 33`

`=> 2^x + 1 = 33`

`=> 2^x = 33 - 1`

`=> 2^x = 32`

`=> 2^x = 2^5`

`=> x = 5`

Vậy `x = 5`
