## IS 144 a perfect cube?

Is 144 a Perfect Cube? The number 144 on prime factorization gives 2 × 2 × 2 × 2 × 3 × 3. Therefore the cube root of 144 is irrational, hence 144 is not a perfect cube.

## Is 144 a square number Yes or no?

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.

## Which of the following is an irrational number 144?

144 is not an irrational number because it can be expressed as the quotient of two integers: 144 ÷ 1.

## What is the Roman numeral for the number obtained when 144 is divided by 16?

Hence, when we divide 144 by 16 we get 9. Now we have to express 9 in Roman numerals. Hence, option (d) is the correct option.

## Which of the following is not a perfect cube 144?

The number 144 on prime factorization gives 2 × 2 × 2 × 2 × 3 × 3. Here, the prime factor 2 is not in the power of 3. Therefore the cube root of 144 is irrational, hence 144 is not a perfect cube.

## How do you find the LCM of 144?

To find the least common multiple (LCM) of 144 and 180, we need to find the multiples of 144 and 180 (multiples of 144 = 144, 288, 432, 576 . . . . 720; multiples of 180 = 180, 360, 540, 720) and choose the smallest multiple that is exactly divisible by 144 and 180, i.e., 720.

## Is 144 a composite number?

Yes, since 144 has more than two factors i.e. 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144. In other words, 144 is a composite number because 144 has more than 2 factors.

## IS 141 a perfect square?

Is the number 141 a Perfect Square? The prime factorization of 141 = 31 × 471. Therefore, 141 is not a perfect square.

## Is root 2 rational or irrational?

Proof: √2 is irrational. Sal proves that the square root of 2 is an irrational number, i.e. it cannot be given as the ratio of two integers.

## IS 325 a perfect square?

Since 325 is not a perfect square, the square root of 325 is a decimal number and not a whole number.

## IS 143 a perfect square?

The prime factorization of 143 = 111 × 131. Here, the prime factor 11 is not in the pair. Therefore, 143 is not a perfect square.

## Who first invented zero?

## Is 000 a real number?

Yes, 0 is a real number in math. By definition, the real numbers consist of all of the numbers that make up the real number line.

## What is R * in math?

In mathematics, the notation R* represents the two different meanings. In the number system, R* defines the set of all non-zero real numbers, which form the group under the multiplication operation. In functions, R* defines the reflexive-transitive closure of binary relation “R” in the set. 4 (4)

## How many divisors does 144 have?

Finding the number of divisors of n Begin by forming the prime factorization of 144: 144 = 24 . 32. From the table, it’s easy to see that there are 5 x 3 = 15 divisors of 144.

## IS 243 is a perfect cube?

∴ 243 is not a perfect cube. Thus, the smallest required number to multiply 243 to make it a perfect cube is 3. (ii) We have 256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2. Grouping the prime factors of 256 in triples, we are left over with 2 × 2.
