simplify log_{2}(28)

Solution

simplify

lo g_{2} (28)

Solution

2 + lo g_{2} (7)

+1

Decimal Notation

4.80735 \dots

Solution steps

lo g_{2} (28)

Factor the number:

28 = 2^{2} \cdot 7

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

Apply log rule:

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

lo g_{2} (2^{2} \cdot 7) = lo g_{2} (2^{2}) + lo g_{2} (7)

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

Apply log rule:

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

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

= 2 + lo g_{2} (7)
