Question

You take out a ₱20,000 loan at a 5% interest rate. If the interest is compounded 
annually,
a. give an exponential model for the situation; and
b. how much will you owe after 10 years?

B. Solve for the value of ? of the following logarithmic equations.
1. log5
(? + 8) = 3
2. log5 25 = ?
3. log5 25 = 3? − 3
4. log10(2? + 1) = 2
5. log5
(? + 3) = log5(22)
C. Find the value of the following logarithmic expressions.
1. log3 81
2. log169 13
3. log5(
1
5
)
4. log9 1
5. 4log8 8
