simplify log_{5}(125x)

Solution

simplify

lo g_{5} (125 x)

Solution

3 + lo g_{5} (x)

Solution steps

lo g_{5} (125 x)

Factor the number:

125 = 5^{3}

= lo g_{5} (5^{3} x)

Apply log rule:

lo g_{a} (x y) = lo g_{a} (x) + lo g_{a} (y)

lo g_{5} (5^{3} x) = lo g_{5} (5^{3}) + lo g_{5} (x)

= lo g_{5} (5^{3}) + lo g_{5} (x)

Apply log rule:

lo g_{a} (a^{b}) = b

lo g_{5} (5^{3}) = 3

= 3 + lo g_{5} (x)
