Hello,
Here's the answer :-
194 * 198
= (196-2)(196+2)
= (196)^2 - (2)^2
= (190+6)^2 - 4
= 36100+2280+36 - 4
= 38412
Hope it helped :-)

There is no such identity for multiplying these two numbers. But I'll give you one way to solve:
190+4*190-1
190(190+4) - 1(190+4)
36100+760-190+4
36100+570+4
36674
190+4*190-1
190(190+4) - 1(190+4)
36100+760-190+4
36100+570+4
36674
