Question 983677
u=log (en base 5) 0.04
u=log(5,0.04)
{{{u=log(5,0.04)}}}


Choosing "common logs", base 10


Formula for Change of Base:
{{{log(5,0.04)=log(10,0.04)/log(10,5)}}}


{{{log(10,(4*10(-2)))/log(10,5)}}}


{{{(log(10,4)+log(10,10^(-2)))/log(10,5)}}}


Use table of common logs or scientific calculator
{{{(0.60206-2)/0.69897}}}
{{{highlight(u=-2)}}}
