After every 2 years, a certain computer loses half of its value. Let the initial price of the computer be x .
So after 2 years, the price reduce to half of its price , that is 0.5x .
After 4 , years, the price reduce to half of its price , that is 0.25x .
After another 2 years, that is after 6 years, the price reduce to half, that is 0.125 x .
