Question 1130042
If {{{log(b,x) = (1/2)log(b,v) + (3)}}} , show that {{{x = (b^3)sqrt(v)}}}


{{{log(x)/ log(b)= (log(v^(1/2))/log(b)) + 3}}}...........change the base


{{{log(x)=(log(b)*log(v^(1/2)))/log(b )+ 3log(b)}}}



{{{log(x)=(cross(log(b))*log(v^(1/2)))/cross(log(b ))+ 3log(b)}}}



{{{log(x)=log(v^(1/2))+ log(b^3)}}}


{{{log(x)=log((v^(1/2)*b^3))}}}


{{{x=v^(1/2)*b^3}}}


{{{x=b^3*sqrt(v)}}}
