Pure: Chapter 14 - Log Laws Flashcards
1
Q
What are the 3 Main Log Laws
A
Log a(x) + log a(y) = log a(xy)
Log a(x) - log a(y) = log a(x/y)
Log a(x^k) = k log a(x)
2
Q
What is log(1/x) equivalent to
A
Log (1/x) = log(x^-1) = -log (x)
3
Q
What is log a(a) equal to?
A
Log a(a) = 1
4
Q
What is Log a(1) equal to
A
Log a(1) = 0
5
Q
What is Log (1/x) equal to?
A
Log (1/x) = log (x^-1) = - log (x)
6
Q
What should you write this as so there is no fraction the brackets:
Log 2(1/2)
A
Log 2(1/2) = -log 2(3)
