Evaluate each logarithm.
How to solve
logb(n) asks: what power of b gives n? Rewrite it as bx = n and find x by counting how many times you multiply b to reach n (remember logb(b) = 1 and logb(1) = 0).
Example
log4(4) = ___
Answer: 1
Not quite. The answer is
💡 Rewrite in exponential form: log4(4) = x means 4x = 4. Find the power: 41 = 4, so x = 1. So log4(4) = 1.
✓ Correct!
Not quite. The answer is
💡 Rewrite in exponential form: log4(4) = x means 4x = 4. Find the power: 41 = 4, so x = 1. So log4(4) = 1.
