Little Math Problem

[th3g00n]

I can't make heads or tails of it.

(4^x) x (16^2x-2) / (4^2x-3) x (128) = ?

NOTE: The (x) in the brackets are variables while those outside are multiplication signs. Anything in front of (^) is an index.

euhh.. sorry for bad image quality 

[th3g00n]

You are wrong dude.

EDIT: Finally got it. I just overlooked a minor detail(you too z3ro).

[z3ro]

really?     what did I miss? 

[th3g00n]

(4^2x-3) becomes (2^4x) x (1/4^3).

Here's my method, love the powers of 2 there

[z3ro]

why is mine wrong?     you got what as final answer?

[s3my0n]

Can't you see lol?

I got 2^(6x-9) as can be clearly seen from the image.

[th3g00n]

I got 2^(6x-9) as can be clearly seen from the image.

The answer is 2^(6x-7)

(4^2x-3) becomes (2^4x) x (1/4^3).

And this is the reason.

[s3my0n]

The answer is 2^(6x-9), check it by replacing x with any number, the original statement will equal to this one.

yaa.got it. I missed a negative 7     lol     i put + 7 instead
