What is the value of 4 power?

Answer and Explanation: When a number is said to be ‘to the fourth power,’ that just means that you need to multiply the number by itself four times.

Which of the given number is divisible by 11?

Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.
