Answer:

1458

Step-by-step explanation:

first of all write 18*81 vertically

1 8

8 1

--------

08-65-08

so first if we see on the right side of these we have 8 and 1 so whenever we multiply 8 and 1 we get 08 later we see here diagonally one and one and if we see this diagonal we have 8 and 8 if we multiply 8 and 8 then we get 64 by multiplying one and 1 whe get 1 now we have both one and 64 so by adding 64 and 1 we get 65 that is written in the middle now coming to the left we have 1 and 8 if we multiply 1 and eight we get 08 that we have written on the left so we finally we got that so now forgetting the final answer first write the unit place of rightmost number that is 8 in in units place of the given answer place and later add tens digit of right mast digit and units place of middle digit that is 0,5 then we get 5 later we have tens digit of of middle number and units place of leftmost number so finally we get 14 by adding 8 and 5 that we write in the answer as shown in the picture above
