- A=1
B=4
141*141 = 19881
ABA*ABA=ADEEA
So, E=8
141+141=282
but E=8 then, 2E2 - 5 years agoHelpfull: Yes(10) No(1)
- 1st unit digit A* 2nd unit digit A= unit digit A,
Hence unit digit A should be either 1, or 5, or 6.
But here adding the unit digits 1,& 6 only gives unit digit '2', i.e, from ABA+ABA ,A+A=2,
on which 2E2 dominates the result. - 5 years agoHelpfull: Yes(3) No(0)
- A=1,B=4
Then ABA*ABA=
141*141=19881
A=1,D=9 E=8E=8 A=1
ABA+ABA=282 - 5 years agoHelpfull: Yes(2) No(0)
- A=1
B=2
E=4
121*121=14641
121+121=242=2E2 - 5 years agoHelpfull: Yes(0) No(9)
- A=1
B=2
E=4
121*121=14641
121+121=242=2E2 - 5 years agoHelpfull: Yes(0) No(2)
- It's option a: 2E2
