simplify log_{sqrt(2)}(64)

Solution

simplify

lo g_{2} (64)

Solution

12

Solution steps

lo g_{2} (64)

Apply radical rule:

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

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

= lo g_{2^{\frac{1}{2}}} (64)

Apply log rule:

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

lo g_{2^{\frac{1}{2}}} (64) = \frac{1}{\frac{1}{2}} lo g_{2} (64)

= \frac{1}{\frac{1}{2}} lo g_{2} (64)

Factor the number:

64 = 2^{6}

= \frac{1}{\frac{1}{2}} lo g_{2} (2^{6})

Apply log rule:

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

lo g_{2} (2^{6}) = 6

= \frac{1}{\frac{1}{2}} \cdot 6

\frac{1}{\frac{1}{2}} \cdot 6 = 12

= 12
