` 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`
