Question

I just need to know how to factor out the 9's and why when you factor out the 9's it becomes 9(3ln(2)+ln(3))

Answer 1

9ln(2)+9ln(12)

Answer 2

n(a+b) = na + nb

Answer 3

its just multiplication; and to factor it out you simply divide it off

Answer 4

the: 3ln(2)+ln(3) : part tho, i cant make sense of that as of yet

Answer 5

ln(2) + ln(12) = ln(2*12)

ln(24) = ln(8*3)

ln(8*3) = ln(2^3) + ln(3)

ln(8*3) = 3ln(2) + ln(3)

Answer 6

For a short video on the distributive property, see

Answer 7

they just seem to be manipulating the ln properties to "simplify" things

Answer 8

yea, if you check out the previous post, two people replyed to this question already
