Question 36250
{{{log x = -2.91}}} actually means {{{log(10, x)= -2.91}}}


This means in exponential form that {{{10^-2.91 = x}}}.  You will probably need a calculator to calculate this:  x = 0.0012302688 approximately.  You can round this off to 0.001 or you could also write it in scientific notation {{{ x= 1.23*10^-3}}}
