Question

2x-2⁰=3⁵:3³

Answer 1

2.x-2⁰=3⁵:3³

=>2.x-1=3²

=>2.x-1=9

=>2.x=9+1

=>2.x=10

=>x=10:2

=>x=5

Vậy x=5

Answer 2

<=>2x-1=3²

<=>2x=9+1

<=>2x=10

<=>x=5

 

Answer 3

4.x+18:2=13

=>4.x+9=13

=>4.x=13-9

=>4.x=4

=>x=4:4

=>x=1

Answer 4

`2x - 2^0 = 3^5 : 3^3`

`2x - 2^0 =` \(3^{5-3}=3^2\)

`2x = 3^2 + 2^0`

`2x = 9 + 1`

`2x = 10`

`x = 10 : 2`

`x = 5`

Vậy `x = 5`
