The learning curve formula is Tn = T1 * n^(log b / log 2), where Tn is the time it takes to produce the nth unit, T1 is the time it takes to produce the first unit, n is the unit number, and b is the learning curve percentage (in decimal form). For the eighth unit (n=8) with a 90% learning curve (b=0.9), the formula becomes T8 = 10 * 8^(log 0.9 / log 2), which calculates to approximately 7.29 hours.
