Explanation

HCF Stand for Highest Common factor

So the HCF of 60 and 72 is 2 × 2 × 3 which is 12.

..........

The lowest common multiple is found by multiplying all the factors which appear in either list

...........

So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

Explanation

Step 1: Calculate the square of 4.

4^2 = 16

Step 2: Double the square of 4.

2×16=32

Step 3: Identify the positive integers that are multiples of 3 and less than 32.

The multiples of 3 below 32 are:

3,6,9,12,15,18,21,24,27,30

Step 4: Focus on the number 18.

18 is indeed a multiple of 3.

18 is less than 32 (which is double the square of 4).

Thus, 18 satisfies both conditions, making it one of the correct answers to the problem.

Explanation

A decade consists of 10 years.

It is a period of ten consecutive years.

Explanation

892 squared, (892)2, is the number you get when multiplying 892 times 892.

It can also be looked at as exponentiation involving the base 892 and the exponent 2.

The square of 892 is a perfect square because the number is the product of the two equal integers 892.

It can be written as 892 × 892 or in exponential form.

Explanation

The set {0} contains exactly one element, which makes it a singleton set.

A singleton set is defined as a set that has only one element.

Explanation

A prime number has exactly two factors: 1 and itself.

The number 1 is not a prime number because it has only one factor (itself).
