Question 545062
Use logs
{{{ 1.43 = 1.05*( 1 + g )^4 }}}
{{{ log( 1.43 ) = log( 1.05 ) + 4*log( 1 + g ) }}}
{{{ 4*log(( 1 + g )) = log( 1.43 ) - log( 1.05 ) }}}
{{{ log(( 1 + g )) = ( log( 1.43 ) - log( 1.05 ) ) / 4 }}}
I don't have a calculator right now, but you
will end up with:
{{{ log(( 1 + g )) = n }}} ( n is some number )
Change this to the form
{{{ 10^n = 1 + g }}} 
{{{ g = 10^n - 1 }}}
Hope this helps
