If the relative error of m is 1% and of h is .5%, what is the error of log(mh)?

2. Relevant equations

d/dx(lnx)=1/x, [tex]\delta[/tex]lnx=[tex]\delta[/tex]x/x

3. The attempt at a solution

[tex]\delta[/tex](ln0.43(mh))=[tex]\delta[/tex](0.43lnm + 0.43lnh)

=[tex]\delta[/tex](0.43ln0.01 + 0.43ln0.005)

=-4.26

i'm pretty sure this isn't right since it's a negative number, i have no idea how to do this
