Hi Nilosree,
 
Do you want to write this in log form or you want to evaluate 1.5 11 ?
 
Log form
log1.5W = 11
 
W is equal to 86.498 rounded to the nearest thousandths

You will apply change of base formula, where you change the base to either base 10 or ln
 
Ex.  log28  change that  to
 
       log8
      ------
       log2
 
you basically will set up a fraction, log base ten of the two numbers of the original log. Easy way to remember, look how the 2 and the 8 are positioned, 8 is kinda on top and 2 is at the bottom, thats the same positioning when you do change of base, top number goes on top and the bottom number goes at the bottom .
 
Hope it helps
