12 cards from this deck
Reverse operation of raising numbers to powers
am=n↔logan=ma^m = n \leftrightarrow \log_a n = mam=n↔logan=m
The base (must be positive and not equal to 1)
The power or index
loga(xy)=logax+logay\log_a(xy) = \log_a x + \log_a yloga(xy)=logax+logay
loga(xy)=logax−logay\log_a(\frac{x}{y}) = \log_a x - \log_a yloga(yx)=logax−logay
loga(xp)=plogax\log_a(x^p) = p \log_a xloga(xp)=plogax
loga(ax)=x\log_a(a^x) = xloga(ax)=x
If logab=logac\log_a b = \log_a clogab=logac, then b=cb = cb=c
ln\lnln (instead of loge\log_eloge)
