simplify log_{2}(4n)

Solution

simplify

lo g_{2} (4 n)

Solution

2 + lo g_{2} (n)

Solution steps

lo g_{2} (4 n)

Factor the number:

4 = 2^{2}

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

Apply log rule:

lo g_{a} (x y) = lo g_{a} (x) + lo g_{a} (y)

lo g_{2} (2^{2} n) = lo g_{2} (2^{2}) + lo g_{2} (n)

= lo g_{2} (2^{2}) + lo g_{2} (n)

Apply log rule:

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

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

= 2 + lo g_{2} (n)
