Question

expression that is equal to ln(10 x) - ln(2 x)?

Answer 1

is it ln(10 x)/ln(2 x) ?

Answer 2

= ln(10) + ln(x) - ln(2) - ln(x)
=ln(5)
(because ln(ab) = ln(a) + ln(b)

Answer 3

what if it was ln(9 x^2)/(ln (3 x))?

Answer 4

qoutient rule? right

Answer 5

= ln((3x)^2) / ln(3x)
=2 * ln(3x) / ln(3x)
=2
because ln(a^b) = b*ln(a)

Answer 6

ok thanx
