## key10 2 years ago Write the expression as a single natural logarithm. 3ln3 + 3lnc A. ln(27 + c3) B. ln9c3 C. ln27c D. ln27c3

1. abb0t

$aln(b) = \ln(b^a)$

2. abb0t

$\ln(a) + \ln(b) = \ln(ab)$

3. ghazi

$3 \ln 3 +3 \ln c =\ln (3)^3+ \ln (c)^3=\ln 27+\ln c^3=\ln(27c^3)$

4. ghazi

$\ln a + \ln b = \ln(ab)$
