lo g_{2} (16)

Solution

4

Solution steps

lo g_{2} (16)

Rewrite

16

in power-base form:

16 = 2^{4}

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

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

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

= 4 lo g_{2} (2)

Apply log rule:

lo g_{a} (a) = 1

lo g_{2} (2) = 1

= 4 \cdot 1

Multiply the numbers:

4 \cdot 1 = 4

= 4
