Answer :

Given, 32^{2}

Need to find out it is divisible by 4 or 8 or both.

⇒ 32^{2} can be written as 1024

⇒ Now, by divisibility rule we have (10c + d) must be divisible by 4

⇒ 1024 is divisible by 4. Since, 10(2) + 4 = 24 is divisible by 4.

⇒ Now, by divisibility rule we have (100b + 10c + d) must be divisible by 8.

⇒ 1024 is divisible by8. Since, 100(0) + 10(2) + 4 = 24 is divisible by 8.

Hence, 32^{2} is divisible by both 4 and 8.
