(2 log(125))/(3 log(25))
= (2 log(5^3))/(3 log(5^2))
=(6 log(5))/(6 log(5))
=1

i assume your log base is 10
just punch in your calculator..
2log125÷3log25
and you'll get the answer

Before starting, you have to know that:
Ln(a)^n = n.Ln(a)
Ln(ab) = Ln(a) + Ln(b)
Ln(a/b) = Ln(a) - Ln(b)
Ln(e) = 1
Ln(x), to be defined, x must be as: x > 0
= [2.Ln(125)] / [3.Ln(25)]
= [2.Ln(5)³] / [3.Ln(5)²] â you know that: Ln(a)^n = n.Ln(a)
= [(2 * 3).Ln(5)] / [(3 * 2).Ln(5)]
= [6.Ln(5)] / [6.Ln(5)]
= 1
