Given that computational speed multiplies by a factor of 4 about every three years.

For computational speed today = s

Computational speed after 1 three-year period = s * 4 = s * 4^1

Computational speed after 2 three-year periods = s * 4 * 4 = s * (4^2)

Computational speed after 3 three-year periods = s * 4 * 4 * 4 = s * (4^3)

Computational speed after x three-year periods = s * (4^x)
