Guys I want to know how I can solve this


5^x-2-5^x-3=20

and

8^3x-5=0.125*( √2/4 )^6-5x

I need to know how to solve this as soon as possible please.

First, one probelm per thread.

Second, we don't do homework on this site. What have you tried with the first one? Hint: \(\displaystyle 5^{x-2}=5^x5^{-2}\)

It isn't reasonably feasible to try to teach classroom lectures through this format. So, to get to where you "know how to solve this as soon as possible", I would recommend that you try studying some online lessons (link).

Please study at least two lessons from the link, and then attempt the exercises. If you get stuck, you can then reply with a clear listing of your efforts so far, at which point we can begin to work with you for your success. Thank you! ;-)
