Answer

$= \ln \frac{16807a^{2}b^{4}}{c^{3}d^{2}} $

Work Step by Step

$ = 5 \ln 7 + 2 \ln a + 4 \ln b - 3 \ln c - 2 \ln d$ $= \ln 7^{5} + \ln a^{2} + \ln b^{4} - \ln c^{3} - \ln d^{2}$ $= \ln 16807 + \ln a^{2}b^{4} - \ln c^{3} - \ln d^{2}$ $= \ln 16807a^{2}b^{4} - \ln c^{3} - \ln d^{2}$ $= \ln \frac{16807a^{2}b^{4}}{c^{3}d^{2}} $
