Logarithm question :)

Question

Log²₂₅125-log²₂₅5

I got 1 as my initial answer but apparently it’s wrong :(

Answer 1

25^3/2 = 5³ =125

25^1/2 = 5

log² 125= 9/4

log² 5 = 1/4

9/4-1/4 = 2

Answer 2

Log²₂₅125-log²₂₅5 = (log₂₅125+log₂₅5)(log₂₅125-log₂₅5) - difference of squares

= log₂₅(125*5) * log₂₅(125/5)

= log₂₅625 * log₂₅25 = 2*1 = 2
