Giúp mik vs ạ ( mik cảm ơn )

`1.`

`2^x = 4^3`

`⇒ 2^x = ( 2^2 )^3`

`⇒ 2^x = 2^6`

`⇒ x = 6`

Vậy `x = 6`

`2.`

`2^x = 4^6`

`⇒ 2^x = ( 2^2 )^6`

`⇒ 2^x = 2^12`

`⇒ x = 12`

Vậy `x = 12`

`3.`

`3^x = 9^10`

`⇒ 3^x = ( 3^2 )^10`

`⇒ 3^x = 3^20`

`⇒ x = 20`

Vậy `x = 20`

`4.`

`2^x = 8^3`

`⇒ 2^x = ( 2^3 )^3`

`⇒ 2^x = 2^9`

`⇒ x = 9`

Vậy `x = 9`

`5.`

`2^x = 8^9`

`⇒ 2^x = ( 2^3 )^9`

`⇒ 2^x = 2^{27}`

`⇒ x = 27`

Vậy `x = 27`

`6.`

`3^{2x+2} = 9^{10}`

`⇒ 3^{2x+2} = ( 3^2 )^10`

`⇒ 3^{2x+2} =  3^{20}`

`⇒ 2x + 2 = 20`

`⇒ 2x = 18`

`⇒ x = 9`

Vậy `x = 9`
