Tìm x thỏa mãn (3x - 1)^10 = (3x - 1)^20

To solve this equation, we can divide both sides by (3x-1) raised to the power of 10:

(3x-1)^10 = (3x-1)^20

(3x-1)^10 / (3x-1)^10 = (3x-1)^20 / (3x-1)^10

1 = (3x-1)^10

Since any number raised to the power of 10 and then to the power of 20 will always be equal to the number raised to the power of 20, the solution to this equation is:

3x-1 = 1

3x = 2

x = 2/3

Therefore, the solution to the equation is x = 2/3.
