Question 1004047
1)  solve the logarithm equation for x:  2ln 3x =8
ln(3x) = 4
3x = e^4
{{{x = e^4/3}}}
------------------------------
2)    solve the exponential equation for x: 20e ^5x= 60
e^(5x) = 3
5x = ln(3)
x = ln(3)/5
=====================

3)     use the properties of logarithm to expand the expression as a sum, difference, and or constant multiple of logarithm (with no exponents): in Square root x/y^3
Not clear.
=========================
4)    evaluate f (x) = 5ln x x=3.27
f(3.27) = 5ln(3.27)
Just calculator work.
