Solving Logs 1
The first of 4 skills relating to logarithms actually doesnot require any logs at all.
If the bases are equal then the powers must be equal.
If 2x = 2y and since 2 = 2 then x = y.
equal bases
Solving Exponential Equations
equal powers
  k + 1 = 2k
-k           -k
Since bases are equal,
equate powers.
Example:
When bases are equal.
1 = k
Solving Exponential Equations
Example:When bases are different.
Now that bases are equal,equate powers.
5•(2p+2) = 210p + 10 = 210p = -8
Re-express with the same base.
25•(2p+2) = 22
p = -8/10
p = -4/5
base of 2
