Question

Math help

Answer 1

Write the given expression as a single logarithm.

Answer 2

\[\ln a + \ln b = \ln(a*b)\]
\[b ln (a) = \ln (a^{b})\]
use these 2 formulas

Answer 3

Your answer is correct, but your steps are wrong.
\[\ln x + 3\ln y \neq 3 \ln(xy)\]
Because:
\[3 \ln(xy) = 3 (\ln x + \ln y) = 3\ln x + 3 \ln y\]

So you have to put the 3 into the exponent first.
