a) ln(2x+5)+2ln(3x+2)
b) 2ln(6x^2+19x+10
c) ln(2x+5)+ln(3x+2)+ln2
d) 2[ln(2x+5)+ln(3x+2)]
Read Solution (Total 3)
-
- ln(a*b^2)=lna+lnb^2=lna+2lnb
so ln((2x+5)*(3x+2)^2)=ln(2x+5)+2ln(3x+2) - 10 years agoHelpfull: Yes(5) No(0)
- a is the right answer.
bcos ln((2x+5)(3X+2)^2)=ln(2x+5)+ln(3x+2)^2)=ln(2x+5)+2ln(3x+2) - 10 years agoHelpfull: Yes(0) No(0)
