Question

(3.x-2) mũ 3=2.32 giúp mình với

 

Answer 1

`@` `\text {Ans}`

`\downarrow`

`(3x - 2)^3 = 2*32`

`=> (3x - 2)^3 = 2*2^5`

`=> (3x - 2)^3 = 2^6`

`=> (3x - 2)^3 = 4^3`

`=> 3x - 2 = 4`

`=> 3x = 6`

`=> x = 6 \div 3`

`=> x = 2`

Vậy, `x = 2.`

Answer 2

=>(3x-2)^3=64

=>3x-2=4

=>3x=6

=>x=2
