yes yes i finally solved my homework equation!!!!!!!!!

Question.....

6) a) Let f(n) be the number of letters used when writing out the digits of the base ten representation of n. For example, f(27) = 8 since ``two seven" has eight letters. What is the value of f(f(f( ?f(216)))) where f is applied 10 times?

Answer

f(216) = f(65536) = 3 + 4 + 4 + 5 + 3 = 19

f(f(216)) = f(19) = 3 + 4 = 7

f(f(f(216))) = f(7) = 5

f(f(f(f(216)))) = f(5) = 4

f(f(f(f(f(216))))) = f(4) = 4

haha 4 will be there forever and thats it!!!

Functions

well as you know maths A levels are split into AS and A2 levels

AS is very easy just like GCSE but A2 is harder than the previous A-levels!!! and this is higher A2 maths

teacher gave us this question he said its one of the hardest you will face and if you do this you can get through the exam...

man come on you must have done these... you even get functions at GCSE!
