Thread: Mixed problems

1) Prove that the equation nDeriv(a^x, x, 1) = e

2) During an attempt increases the amount of bacterias y in 1 litres milk according to y = 10 * 2^x, where x is the time in hours.
Solve the equation y'(x) = 1 000 and explain the result.

Mr F says: Do you mean nth derivative of a^x evaluated at x = 1?

2) During an attempt increases the amount of bacterias y in 1 litres milk according to y = 10 * 2^x, where x is the time in hours.
Solve the equation y'(x) = 1 000 and explain the result.
Mr F says: Do you know how to differentiate 2^x ?

These are NOT Pre-algebra and algebra questions. They clearly should have been posted in the Calculus forum.
