Answer 2

Question :- If unit place of a number is 6 then

what will be the unit place of its cube ?

Solution :-

Unit place of a numbers of cube is depend upon the unit place of the given number.

And,

unit place of all the numbers is different.

Unit place of cubes :-

→ 1³ = 1 => unit place of number with 1 will always gives 1 as unit place in cube.

→ 2³ = 8 => unit place of number with 2 will always gives 8 as unit place in cube.

→ 3³ = 27 => unit place of number with 3 will always gives 7 as unit place in cube.

→ 4³ = 64 => unit place of number with 4 will always gives 4 as unit place in cube.

→ 5³ = 125 => unit place of number with 5 will always gives 5 as unit place in cube.

→ 6³ = 216 => unit place of number with 6 will always gives 6 as unit place in cube.

→ 7³ = 343 => unit place of number with 7 will always gives 3 as unit place in cube.

→ 8³ = 512 => unit place of number with 8 will always gives 2 as unit place in cube.

→ 9³ = 729 => unit place of number with 9 will always gives 9 as unit place in cube.

Therefore,

→ If unit place of a number is 6 then the unit place of its cube will depend upon cube of unit digit only = 6³ = 216 = 6 in Last .

Hence,

Unit digit of required cube is also 6.
