Question

write the expression as the logarithm of a single quantity

3[ln x-2 ln(x^2+1)]+2 ln 5

Answer 1

3logx-6log(x^2+1)+log25
logx^3-log(x^2+1)+log25
logx^3+log25-log(x^2+1)^6
log(x^3*25/(x^2+1)^6))

Answer 2

wait, may I ask you what happened to ln?

Answer 3

it is the same thing bro log and ln

Answer 4

ln is log base e

3[ln x-2 ln(x^2+1)]+2 ln 5

ln a - ln b = ln (a/b)
n ln x = ln x^n
so
3 ln [ x/(x^2+1)^2] + ln 25

ln 25[ x/(x^2+1)^2]^3
so agree with Sam
