1. ## Show that...

$5^{2k+2}-5^{2k} = 24 * 5^{2k}
$

thanks

2. 1) factor out 5^2k
5^(2k)(5^2-1)
2) simplify
5^(2k)(24)
so

4. No! It took me a few minutes to think about what I needed to do. I am in school right now and my major is secondary mathematics education, so it is important for me to actually know this!Don't lose confidence! If you cant figure out a problem the first time, leave it and come back later!
