SOLVE FOR X

nowhereman · Answer

what?

anonymous · Answer

mmm?

anonymous · Answer

$$(1 \ 3)^{4x-1}=3^{x-1}$$

anonymous · Answer

(1/3)*****

nowhereman · Answer

well, you know exponentiation rules, don't you?

anonymous · Answer

not really.. :x

nowhereman · Answer

anonymous · Answer

x≈0.4

anonymous · Answer

I dont understand what that means can you show me how you got that answer norbeybarajas

anonymous · Answer

anonymous · Answer

-________- I dont understand what im looking at when i look at that..

nowhereman · Answer

you have to multiply the equation by $3^{4x-1}$ to get all the x on one side and then you just simplify, until you can take the logarithm.

anonymous · Answer

i still dont understand but thanks

nowhereman · Answer

Then show your calculations and where you don't know what to do.

anonymous · Answer

i dont even know how to start the problem..

nowhereman · Answer

I just told you.

anonymous · Answer

where are you getting that though you combined both sidfes of the equal sign..

nowhereman · Answer

If you multiply both sides by that term you will get just "1" on one side and the terms with x on the other.

anonymous · Answer

I really dont understand what your saying where did you get 3^4x-1   its either 3^x-1  or 1/3^4x-1

nowhereman · Answer

$3^{4x-1} \cdot (\frac{1}{3})^{4x-1} = 1$
that is why you should really look at those rules!

anonymous · Answer

I did/ i am i dont know what im even looking at !!!!! :[ i just need someone to explain it from the first to last step or before i can solve it..

nowhereman · Answer

Maybe you should start with some easier exponential calculations then.

anonymous · Answer

This is on a passed regents exam..... i dont even remeber doing this
