Math guys look here please

[Bansh-eman]

ok guys if you understand how to do this problem please post and show how u got it. the ^ shows an exponant so ^ 6x-5 is the exponant of 125

 

5^x x 125^6x-5

[LiftdT4R]

Shouldnt it be 5^x * 125^(6x-5) or 5^x = 125^(6x-5)? It's hard to tell the way it's typed.

I'm guessing it is 5^x * 125^(6x-5) = some number. So if you want to simplify it, apply the natural log to both sides, and on the left you will get (19-x)*ln(5), by the ln rules for addition and multiplication.

Well, what was the answer?

You have to give it the natural log......... :biggrin:

If I was given the problem he first stated I could only say f(x) is equal to some positive number. If you gave me what the equation was equal to, I could tell you what x was , by yes, using a log function on both sides and solving for x. It threw me where he dosen't equal the equation to something. Out of habit I tried to equal it to 0 and realized I was going down the wrong path.
