Question

I need help with this math problem.

Answer 1

In logarithms multiplication becomes addition when you want to expand:

`ln3+ln x^(4) +ln y^(7)`

To convert a base of something else to base 10 you divide the two with each at base 10;

`( log_(10)5x )/( log _(10)4 )`

Hope that helps

Answer 2

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

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