in logarithim questions make every value in the form of log remember log base 5 5=1, log base 2 2=1 and so on. if you want to convert a whole number to log form, example the value 2, to log base 3, then log base 3 x=2. to find x, x=3^2, x=6 therefore log base 3 6=2. properties of log: log A+ log B= log (A*B)

with exponentials introduce natural log ln. ln e^3x=5/2 note we have divided both sides by 2

ln e^3x can be writen as 3x ln e=5/2

but ln e=1

3x=5/2

x=(5/2)*(1/3

x=5/6 please rectify the answer to question b) x=5/6
