    Hahah :P, lool nah they have difficulty pronouncing my name so call me Pie for short
    My friend randomly made it up for me at my old school and ended up coming in use! Sometimes if we have a sub teacher and they say my real name people get confused like whos that?

    I do love food though....:love:
    Lol. I knew a girl who was called Pi too, though this was a nickname because their name was too long o.O

    Thats nothing, in my chemistry lesson my teacher put me on the spot asked me to say which type of alcohols each structure was, I didn't have my book on me OR the h/w and just randomly said 'primary etc' and got them all right, my friend was pissing herself with laughter LOOL everyone knew I guessed it all
    Got them all right? That's pretty lucky... how many structures were there?

    The funniest was in my Spanish class at GCSE, the teacher asked my friend sitting next to me to say what 'the head' is in Spanish - he didn't know so I whispered 'la polla' in his ear and he said it :teehee:

    Well, that's how it goes
    Let's see . . .
    Got another problem for you.
    If \log_{10}2=x and \log_{10}3=y
    Express \log_5(36) in terms of x and y.
    Can you post hints/solutions for this question please? Thanks

    How about:
    I = \displaystyle\int^9_4 \dfrac{\ln(x-1)}{\sqrt{x}} \ dx
    I've probably gotten this wrong too
    My answer:
     \left[ 2\sqrt{x}ln(x-1)-ln(x-1) \right]_4^9

    Sadly yes, it's incorrect.

    Consider x+y.
    You may also need the change of base formula - you can quote it without proof

    \log_{10} 4 + \log_{10} 9 = 2x + 2y = \log_{10} 36

    \log_{5} 36 = \dfrac{\log_{10} 36}{\log_{10} 5} = \dfrac{2x + 2y}{\log_{10} 10 - \log_{10} 2} = \dfrac{2x + 2y}{1-x}
