lo g_{2} (8)

Solution

3

Solution steps

lo g_{2} (8)

Rewrite

8

in power-base form:

8 = 2^{3}

= lo g_{2} (2^{3})

Apply log rule:

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

lo g_{2} (2^{3}) = 3 lo g_{2} (2)

= 3 lo g_{2} (2)

Apply log rule:

lo g_{a} (a) = 1

lo g_{2} (2) = 1

= 3 \cdot 1

Multiply the numbers:

3 \cdot 1 = 3

= 3
