Question 607344
{{{log(8.9, (124))}}}
Just use the change of base formula, {{{log(a, (p)) = log(b, (p))/log(b, (a))}}}, to convert this base 8.9 log into an expression of ln's:
{{{log(8.9, (124)) = ln(124)/ln(8.9)}}}
Now get out your calculator:
{{{log(8.9, (124)) = ln(124)/ln(8.9) = 4.82028157/2.18605128 = 2.20501761}}}
Rounded to 4 decimal places we get:
2.2050
