Solution

simplify

ln (9) - ln (1)

Solution

2 ln (3)

+1

Decimal Notation

2.19722 \dots

Solution steps

ln (9) - ln (1)

Apply log rule:

lo g_{a} (1) = 0

= ln (9) - 0

ln (9) - 0 = ln (9)

= ln (9)

Rewrite

9

in power-base form:

9 = 3^{2}

= ln (3^{2})

Apply log rule:

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

ln (3^{2}) = 2 ln (3)

= 2 ln (3)
