Use the Laws of Logarithms to expand the expression ln6x2x
Use the Laws of Logarithms to expand the expression.
ln((6x^2)/((x + 4)^2))
Solution
ln((6x^2)/((x + 4)^2))
Use the laws of logarithms :
ln(A/B) = ln(A) - ln(B) ; ln(A^x) = x*lnA ; ln(A*B) = lnA + lnB
ln((6x^2)/((x + 4)^2))
= ln6x^2 - ln(x+4)^2
= lnx^2 + ln6 - 2ln(x+4)
= 2lnx +ln6 - 2ln(x+4)
