simplify log_{121}(sqrt(11))

Solution

simplify

lo g_{121} (11)

Solution

\frac{1}{4}

+1

Decimal Notation

0.25

Solution steps

lo g_{121} (11)

Factor the number:

121 = 1 1^{2}

= lo g_{1 1^{2}} (11)

Apply log rule:

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

lo g_{1 1^{2}} (11) = \frac{1}{2} lo g_{11} (11)

= \frac{1}{2} lo g_{11} (11)

Apply radical rule:

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

11 = 1 1^{\frac{1}{2}}

= \frac{1}{2} lo g_{11} (1 1^{\frac{1}{2}})

Apply log rule:

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

lo g_{11} (1 1^{\frac{1}{2}}) = \frac{1}{2}

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

\frac{1}{2} \cdot \frac{1}{2} = \frac{1}{4}

= \frac{1}{4}
