Solution

1 + lo g_{10} (2)

+1

Decimal Notation

1.30102 \dots

Solution steps

lo g_{10} (20)

Factor the number:

20 = 10 \cdot 2

= lo g_{10} (10 \cdot 2)

Apply log rule:

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

lo g_{10} (10 \cdot 2) = lo g_{10} (10) + lo g_{10} (2)

= lo g_{10} (10) + lo g_{10} (2)

Apply log rule:

lo g_{a} (a) = 1

lo g_{10} (10) = 1

= 1 + lo g_{10} (2)
