Question

if ln k = 0.7, calculate the value of the following expression:

\[\ln \sqrt[3]{k}/10 + \ln(10k^{2})\]

Answer 1

use these:
1)ln(a/b) = lna -lnb
2)ln(a^b) = b lna
3)ln(ab) = lna + lnb

try now..

Answer 2

using the log runs above

\[\frac{3}{2} \log (k) - \log(10) + \log(10) + 2 \log(k)\]

hopefullt this will help you find the answer.

Answer 3

32log(k)−log(10)+log(10)+2log(k)
=3/2 log (0,7) - log (10) + log (10) + 2 log (0,7)
=3/2 -0,15 -1 +1 + 1,4
=4,25/2
