logarithm rules Flashcards
1
Q
If y = a↑x, then x =
A
x= log🠗a(y)
2
Q
log🠗a(x/y)
A
= log🠗a(x) - log🠗a(y)
3
Q
log🠗a(xy)
A
= log🠗a(x) + log🠗a(y)
4
Q
log🠗a(x↑n)
A
= n log🠗a(x)
5
Q
If y = ln(x), then what does dy/dx equal
A
dy/dx = 1/x
6
Q
If y = ln f(x), then what does dy/dx equal
A
dy/dx = f’(x)/f(x)
7
Q
If y = log🠗a(x), then what does dy/dx equal
A
dy/dx = 1/xln(a)
8
Q
log🠗a(b)
A
1 / log🠗b(a)
