Aim: What are the properties of logarithmic expressions? HW#57 Back of the Lesson Using the properties of exponents we have derived the rules for logarithms.
1 m logb √n m = log n
logb1 = 0
logbb = 1
Rewrite each expression using the rules of logs
1. Logb6= Logb(3*2)
(
(2 = 2. Logb 3
3. Log3a5= 4. Log3a5b=
5. Logx(ab)5= 2
x 6. Logb =
y
7. Logbx√y =
8. Find the values of log42 + log432
9. If logm=x and logn=y, write in terms of x and y the expression log∛mn
10. If log2=m and log6=n, find log48
11. Find the values of log216 log24
12. If logb5= 1.367, what is the logb25?
13. If log2=p and log5=q, express log20 in terms of p and q.
