What is Log Base 10 (log₁₀)?
The common logarithm (log₁₀) answers:
“How many times must we multiply 10 to get a given number?”
Mathematically:
If log₁₀(x) = y, then 10ʸ = x.
Key Properties:
✔ log₁₀(1) = 0 (since 10⁰ = 1)
✔ log₁₀(10) = 1 (since 10¹ = 10)
✔ Used in scientific notation, pH scale, and decibels
✔ Helps measure orders of magnitude
