1. 2 log x + log 4 = 2
2. log(x^2)+log(4)=2
3. log(4x^2)=2
4. 10^2=4x^2
5. 100=4x^2
6. 25=x^2
7. +5=x

1. Equation.
2. Logarithm Exponent Rule: Alog(B)=log(B^A)
3. Logarithm Multiplication Rule: log(A)+log(B)=log(AB)
4. Logarithm Rule Thingy: Logs are base 10, so log(A)=B is also equal to 10^B=A
5. Simplify terms.
6. Divide by 4.
7. Square root.  Find answer.

The answer can't be -5, because when you unlog (I don't know any other terminology, sorry!) something, you find the absolute value, since one can't have a logarithm of a negative number.  For the simpler version of this though; if you find that what's inside the log is negative, it's wrong!!!

QuoteMashi is one of the smartest people I know  :D

That probably helped me just as much as it helped BDS. Thanks!

You flatter me too much. :P
This will become easy to you when you take higher level Maths, don't worry!  I used to be only adequate at Maths, but I've caught up to the Maths obsessed students of my school, so it just takes time and studying!
As expense for my services, you must do well in your Maths class!!!

Math is the only class that I'm not doing well in u_u

I'll try!

Thank you very much Mashi!! :D

Natural logs are better than regular logs. Jussayin.

What math is this XD I feel like its algebra but I've never seen it yet...probably because my algebra teacher was a complete airhead

Nebbles: "tell the people at NSM I do miss them and I'll probably be back this weekend, depending on how I feel."

It's Algebra II

And yay! Come back soon, Nebbles!

Try to do everything; you're bound to succeed with at least one.

I haven't had to do Math in 5 years
That's one of the best things that happened in my life so far, getting rid of math.

Thanks. For a moment there I was worried, though. I almost needed to blow you.

I'm a musician, and unless I want to be the next Iannis Xenakis, the only maths I need are fractions.

I don't need math at all because I'm a translator :3
I've always hated that subject so... good riddance.

I prefer Geometry over Algebra, except for all the long proofs; fortunately, I'll be doing that next year (I've already done Geometry, but I need to retake it in order to get credit with the school ::))
