HW Help

Can anyone help me with these questions??

#1.) ln(e^18/15)
#2) ln[(x^8*sqrt(x^2+3))/((x+7)^11]
#3) 5ln(x+4)-4lnx
#4) 1/7(log(base 2)(x)-log(base 2)(y))+9(log(base 2)(x+4))

Thanks in advance!

That's the problem I don't get how to do any of it

OK I got through the problems except for one. I realized that I wrote it wrong in the inintial question. It reads 5ln(x+11)-4lnx.

I know it would translate to ln(x+11)^5-lnx^4 but then im not sure if i do this--> ln(x+11)^5/x^4. Thanks
