\[5y^8=125\] ---> \[y^8=25\]---->\[y=\sqrt[8]{25}\]

Okay, so the term that 5 and 125 have in common is 5, so you factor that out 125/5=25 so that leaves you with \[5(y ^{8}-25)\]

now, let's look at (y^8-25) y^8 is the same as (y^4)^2 and 25 is the same as (5)^2

which will be a difference of squares so you split it into two (y⁴-5)(y⁴+5) and one has a + and one has a - because the product of a + and - is - and dont forget the 5 up front so the answer is 5(y⁴-5)(y⁴+5)
