Solution

simplify

lo g_{2} (18)

Solution

1 + 2 lo g_{2} (3)

+1

Decimal Notation

4.16992 \dots

Solution steps

lo g_{2} (18)

Factor the number:

18 = 2 \cdot 9

= lo g_{2} (2 \cdot 9)

Apply log rule:

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

lo g_{2} (2 \cdot 9) = lo g_{2} (2) + lo g_{2} (9)

= lo g_{2} (2) + lo g_{2} (9)

Apply log rule:

lo g_{a} (a) = 1

lo g_{2} (2) = 1

= 1 + lo g_{2} (9)

lo g_{2} (9) = 2 lo g_{2} (3)

= 1 + 2 lo g_{2} (3)
