I need help with these 3 problems. Please explain so I can know how to do them. I did try some of them
Find a formula for the inverse of the function.
Find the exact value of each expression.
34. (a) ln(1/e)= -1 I don't if that's right.
36. (b) ln(ln e^e10)
Express the given quantity as a single logarithm.
ln(1+x^2) + 1/2 ln x - ln sin x = ln sq[1+x^2]/ sin x
THis is my first week of college and it's already hard. I have a quiz tomorrow.
You want to solve for x --this gives f^-1(y)
y + 2ye^x = e^x
e^x (2y-1) = -y
e^x = y/(1-2y)
f^(-1) (x) = ln[x/(1-2x)]
34a ln(1/e) = ln(1) - ln(e) I'll let you explain why this is -1
36 Not clear do you mean ln(ln[e^(10e)]) ?
For the last problem use the 3 basic prop
lna + lnb =ln(ab)
ln(a)-ln(b) = ln(a/b)
ln(a^r) = rln(a)
