The Power Rule for Logarithms
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The power rule for logarithms pulls an exponent out front: log_b(Mᵖ) = p · log_b(M).
Show
log₂(8²) = log₂(64) = 6, and 2 · log₂(8) = 2 · 3 = 6 — the exponent steps down to multiply.
Watch for
The exponent must cover the whole input, not one factor of it.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
