first (1/20)^37 taking log to this will give log(1/20)^37

this can be written as (log1-log20)^37

log 1=0

log 20 can be written as -(log 2+log 10)^37

log 10 = 1 log 2=0.3010
10

-37(1+0.3010)
=-48

As we are calculating for the zeroes after decimal the anwer will have negative symbol

these are the formulas used am giving in the order
log(a/b)=log a -logb
loga^m=mlog a
loga*b=log a+logb
