1st problem would be In (3) + 4 In (x) + 7 In (y)

2nd problem would be log4 (5) + log4 (x)
log4 (5) + log4 (×)

In logarithms multiplication becomes addition when you want to expand:
[tex]ln3+ln x^{4} +ln y^{7} [/tex]

To convert a base of something else to base 10 you divide the two with each at base 10;
[tex] \frac{ log_{10}5x }{ log _{10}4 } [/tex]

Hope that helps
