## Why are there no perfect squares between 144 and 169?

Answer. It is clear that 12^2 = 144 and 13^2 = 169. Hence, there are no squares between them.

## Is 49 a cube number?

6, 13, 20, 34, 39, 41, 46, 48, 53, … 7, 14, 21, 42, 47, 49, 61, 77, … There is a finite set of numbers which cannot be expressed as the sum of distinct positive cubes: 2, 3, 4, 5, 6, 7, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, … (OEIS A001476).

## Is 75 a perfect square?

Is 75 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 75 is about 8.660. Thus, the square root of 75 is not an integer, and therefore 75 is not a square number.

## What is the factor for 48?

48 is a composite number. 48 = 1 x 48, 2 x 24, 3 x 16, 4 x 12, or 6 x 8. Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48. Prime factorization: 48 = 2 x 2 x 2 x 2 x 3, which can also be written 48 = 2⁴ x 3.

## IS 121 a perfect square?

The answer is 11. The square root of 121 equals 11. Since 11 is a whole number, 121 is a perfect square.

## What are the factors of 16 and 48?

The gcf of 16 and 48 can be obtained like this: The factors of 16 are 16, 8, 4, 2, 1. The factors of 48 are 48, 24, 16, 12, 8, 6, 4, 3, 2, 1. The common factors of 16 and 48 are 16, 8, 4, 2, 1, intersecting the two sets above.

## Why is 28 the perfect number?

In number theory, a perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. For instance, 6 has divisors 1, 2 and 3 (excluding itself), and 1 + 2 + 3 = 6, so 6 is a perfect number. … For instance, 28 is perfect as 1 + 2 + 4 + 7 + 14 + 28 = 56 = 2 × 28.

## Is 121 a lucky number?

The angel number 121 cannot be bad luck because it resonates with everything good and positive. It carries the energies of trust and faith, which you must have if you are going through a difficult period in your life. Trust that everything you are experiencing is for a higher and bigger purpose.

## Is 24 a perfect square?

Since 102.01 is a rational number and the square root of 102.01 is a rational number (10.1), 102.01 is a perfect square. 24 is NOT a perfect square. 24 is a natural number, but since there is no other natural number that can be squared to result in the number 24, 24 is NOT a perfect square.

## Is 49 a perfect square?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 49 is 7. Therefore, the square root of 49 is an integer, and as a consequence 49 is a perfect square. As a consequence, 7 is the square root of 49.

## IS 400 a perfect square?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 400 is 20. Therefore, the square root of 400 is an integer, and as a consequence 400 is a perfect square.

## What is the greatest prime factor of 48?

The prime factorization of 48 is 2 × 2 × 2 × 2 × 3. We can find the prime factorization of 48 using a factor tree.

## What is the square of 121?

11Student Answers The square root of a number is the answer to a number multiplied by itself. So the square root of 121 is 11 because 11×11=121.

## Is 2 a square number?

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

## Why is 56 not a cube number?

n3 = 56 where n is a whole number. In other words, if n*n*n = 56, then 56 is a cube number. There are no whole numbers you can set to n to make the equation above 56. Therefore, we can conclude that 56 is NOT a cube number.

## Is 40 a perfect square?
