Solution

\frac{5}{4}

+1

Decimal Notation

1.25

Solution steps

lo g_{16} (32)

Factor the number:

16 = 2^{4}

= lo g_{2^{4}} (32)

Apply log rule:

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

lo g_{2^{4}} (32) = \frac{1}{4} lo g_{2} (32)

= \frac{1}{4} lo g_{2} (32)

Factor the number:

32 = 2^{5}

= \frac{1}{4} lo g_{2} (2^{5})

Apply log rule:

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

lo g_{2} (2^{5}) = 5

= \frac{1}{4} \cdot 5

\frac{1}{4} \cdot 5 = \frac{5}{4}

= \frac{5}{4}
