log_a(b)
Pronounced log base a, this function is used to figure out what exponent you need to raise a
to to get b
.
log_ab = c
can be rewritten as a^c = b
.
5^{log_5^(x+2)}=x+2
By default, log
refers to log_{10}
. ln
is shorthand for log_e
.
\sqrt{x} = x^{1/2}
To get the reciprocal of a value, change the sign of the exponent.
x =
