general question: how do i even write equivalent expressions to like a given expression?

the question for example asks for an equivalent expression if you are given 5^4x-3

(sorry i did not know how to write that in latex)

i have tried this question over 5 times and i still dont understand how it can be solved:

can someone please give me some hints, i don't want it to be solved i want to figure it out myself but i really don't know where to start.

thank you :3

There are LOTS of ways to write equaivalent expressions.....is this 5^{4x-3 }?

= 5^{4x} /^{ }5^{3}

^{ }= 5^{4x }/125 are a couple equivalent expressions

Thanks EP

Firstly the expression you have written is not clear.

5^4x-3

EP has interpretted this to mean \(5^{4x-3}\)

**Is this what you intended? **If so it should have been written as 5^(4x-3)

\(5^{4x-3}\\ =5^{4x}*5^{-3}\\ =(5^4)^x*\frac{1}{5^3}\\ =\frac{625^x}{125} \)

this is just another answer that is equivalent.
