"An Exponential Function"
Given the following function:
3^x
What is the first 3 digits of the value of f(50)?
Once you understand the equation it's fairly trivial to write a script for this... remember to read the question carefully especially abdout the awnser it wants!
Awnser:
176

function solution(){ $result = bcadd(bcpow(4, 50), bcpow(50, 3)); $result = bcadd($result, bcpow(50, 2)); $result = bcadd($result, 50); $result = bcsub($result, bcpow(2, 50)); $result = bcdiv($result, bcpow(3, 50)); echo $result[0].$result[1].$result[2]; }
