Answer:

I'll help a bit!

So, we need to have the same base on either side, like this:


EX:4^(7) =4^(x)

Essentially, we need to find the factors of 1024:


1024=4*4*4*4*4

So then, we can write it as:


4^(1+2x) =4^(5)

(As there are 5 4's in the factorization)

So, let's solve!

First step, use the Equality of Bases Property:

It states that:


x^(v) =x^(c)

Then:


v=c

So, continuing on:


1+2x=5\\2x=4\\x=2

Hope this helps!

(hope this also answers your question)

P.S. Ask me if you have any more questions, and remember to wash your hands!
