simplify log_{sqrt(5)}(5x)

Solution

simplify

lo g_{5} (5 x)

Solution

2 + 2 lo g_{5} (x)

Solution steps

lo g_{5} (5 x)

Apply radical rule:

a = a^{\frac{1}{2}}

5 = 5^{\frac{1}{2}}

= lo g_{5^{\frac{1}{2}}} (5 x)

Apply log rule:

lo g_{a^{b}} (x) = \frac{1}{b} lo g_{a} (x), a > 0

lo g_{5^{\frac{1}{2}}} (5 x) = \frac{1}{\frac{1}{2}} lo g_{5} (5 x)

= \frac{1}{\frac{1}{2}} lo g_{5} (5 x)

\frac{1}{\frac{1}{2}} = 2

= 2 lo g_{5} (5 x)

Simplify

lo g_{5} (5 x) : 1 + lo g_{5} (x)

= 2 (1 + lo g_{5} (x))

Expand

2 (1 + lo g_{5} (x)) : 2 + 2 lo g_{5} (x)

= 2 + 2 lo g_{5} (x)
