Question 770169
(b)	36 =(1/6)^-2 

Is a fraction base common for this?

{{{(1/6)^-2=6^2}}}, so the equation could be written, {{{36=6^2}}}.
{{{log(6,36)=2}}}


-------
Note that exponential form shows a base and an exponent applied to that base:
{{{b^n=m}}}, is an equation in exponential form.  The base is b, and the exponent is n.

{{{log(b,m)=n}}} is the same equation in logarithmic form.  n is still an exponent, but here it is called a logarithm.  The base is shown as a subscript on the "log" notation.
