**Can't solve a mathematical equation?, can't remember a particular thing?**

Ask here and see if someone else knows!Ask here and see if someone else knows!

I'll start with my mathematical equation.

a Log (x-5) = a? Log (7-x)

And the "a"'s are not random numbers like 5 times log...but it's the (don't know correct word in english). It's the a like in x?...it's the "macht" (power, wrong free translation)

The general rule is ^g Loga^b = b^g log a

The b is no normal number in my equation! It's the higher (x? one, it's the 2)

^aLog(x-5) = ^a? Log (7-x)

I have this rule: ^g Log (a^b) = b x ^g Log (a)

MXM, Chaos and Raspberri said this rule could be applied here but I still don't think that's possible.

Correct me if I'm wrong..
