Ending DIGIT = 4 and 42 = 16

∴ (1234) will have 6 as the one’s digit.

(ii) ∵ Ending digit is 7 and 72 = 49

∴ (26387)2 will have 9 as the one’s digit.

(iii) ∵ Ending digit is 8, and 82 = 64

∴ (52692)2 will end in 4.

(iv) ∵ Ending digit is 0.

∴ (99880)2 will end in 0.

(v) ∵ 22 = 4

∴ Ending digit of (21222)2 is 4.

(vi) ∵ 62 = 36

∴ Ending digit of (9106)2 is 6.
