If you didn't know strlen() is how to get the number of characters in a string.

`<?php  echo strlen(md5('hash'));?>`

2*sqrt(4)*(8^(1/3))^6Solve for X

? There is no X in that expression... (and to solve you need an equation). :)Jhecht's expression evaluates to 256, by the way.

Typo. was supposed to be 2*sqrt(4)*(8^(1/3))^4Solve for X(weird spacing on this computer, not my laptop)

That still doesn't have an X in it

x=2*2*(2)^4x=4*16x=64?
