simplify ln((1+8)/(2+1))

Solution

simplify

ln (\frac{1 + 8}{2 + 1})

Solution

ln (3)

+1

Decimal Notation

1.09861 \dots

Solution steps

ln (\frac{1 + 8}{2 + 1})

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

ln (\frac{1 + 8}{2 + 1}) = ln (1 + 8) - ln (2 + 1)

= ln (1 + 8) - ln (2 + 1)

Add the numbers:

1 + 8 = 9

= ln (9) - ln (2 + 1)

Add the numbers:

2 + 1 = 3

= ln (9) - ln (3)

ln (9) = 2 ln (3)

= 2 ln (3) - ln (3)

Add similar elements:

2 ln (3) - ln (3) = ln (3)

= ln (3)
