Express as sums, differences, and multiples of logarithms. Expand as much as possible.

Question

ln((x^14 √x+15)/(12x−2)^15)

this is what I got ?
14sqrt(x+15)ln(x)-15ln(12x-2)

check my work please and thanks

Answer 1

Good grief!
Did you even look at the answer I gave you for this same question
I don't think so, because you posted it with the same ambiguous √x+15

Answer 2

You don't have to be rude. It's not the same question. I reposted it bec I posted it wrong the first time. There is no square root sign in the denominator

Answer 3

ln(ab) = lna + lnb
ln(a/b) = lna - lnb
ln(a&n) = n * lna
now use that to evaluate your expression, and post your answer. We can check it to see whether it makes sense.
Don't be stingy with parentheses.
√x+15 is not the same as √(x+15)
√4+15 = 2+15 = 17
√(4+15) = √19

Answer 4

I wish we could post images on Jiska. There was no parantheses . It WAs like x^14√x+15 in numerator//Thank you math helper..sorry if I was rude. I hate math

Answer 5

In that case, you're stuck, since there is no way to simplify ln(a+b)
