## What is the prime factors of 36?

When a composite number is written as a product of all of its prime factors, we have the prime factorization of the number. For example, the number 36 can be written as a product of primes as: 36 = 2² x 3². The expression 2² x 3² is said to be the prime factorization of 36.

## Is 38 a perfect number?

There are currently only 38 known Mersenne primes, so there are only 38 known perfect numbers. The largest perfect number corresponds to the Mersenne prime 26972593 – 1 (a number with over 2 million digits), the perfect number itself has 4197919 digits.

## What are the prime numbers for 38?

38 is a composite number. 38 = 1 x 38 or 2 x 19. Factors of 38: 1, 2, 19, 38. Prime factorization: 38 = 2 x 19.

## Why is the square root of I?

Square roots Because the real and imaginary parts are always separate, we regroup the terms: x2 − y2 + 2i x y = 0 + i. and by equating coefficients, real part and real coefficient of imaginary part separately, we get a system of two equations: … Thus, the square roots of i are the numbers 1/√2 + i/√2 and −1/√2 − i/√2 .

## Is 39 a rational number?

For 39 to be a rational number, the quotient of two integers must equal 39. … The number 39 can be expressed as 39/1 where 39 is the numerator and 1 is the denominator. Thus, the answer to the question “Is 39 a rational number?” is YES.

## Why is 20 not a 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 20 is about 4.472. Thus, the square root of 20 is not an integer, and therefore 20 is not a square number.

## Why is 38 not a prime number?

For 38 to be a prime number, it would have been required that 38 has only two divisors, i.e., itself and 1. However, 38 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 38 = 2 x 19, where 2 and 19 are both prime numbers.

## Is 40 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.

## What is the square of I?

An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25.
