simplify log_{64}(128)

Solution

simplify

lo g_{64} (128)

Solution

\frac{7}{6}

+1

Decimal Notation

1.16666 \dots

Solution steps

lo g_{64} (128)

Factor the number:

64 = 2^{6}

= lo g_{2^{6}} (128)

Apply log rule:

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

lo g_{2^{6}} (128) = \frac{1}{6} lo g_{2} (128)

= \frac{1}{6} lo g_{2} (128)

Factor the number:

128 = 2^{7}

= \frac{1}{6} lo g_{2} (2^{7})

Apply log rule:

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

lo g_{2} (2^{7}) = 7

= \frac{1}{6} \cdot 7

\frac{1}{6} \cdot 7 = \frac{7}{6}

= \frac{7}{6}
