95 watts

10log x = 19.78
log x = 1.978
x= 10^1.978

Or an aproximated way:
0dBW = 1 W
10 dBW = 10 W
20 dBw = 100 W
19.78 is slightly less than 20 so the
answer is 19.78 dBW = 20 dBW - 0.22 dB,
-0.22 dB = 0.9506, so 20 dBw - 0.22 =
100x0.9506 W = 95.06 W

the classic formula is:
db=10log(P)

of here you can get the power in watts
