Numerical Expressions Let’s break down the phrase “the product of a number and a sum” to understand the meaning of this expression. The word product means the results of multiplying two or more numbers. The word sum means the results of adding two or more numbers.

The multiplication of algebraic expressions is a method of multiplying two given expressions consisting of variables and constants. For example, 4xy + 9, in this expression x and y are variables whereas 4 and 9 are constants.

When we multiply two numbers, the answer we get is called ‘product’. The number of objects in each group is called ‘multiplicand,’ and the number of such equal groups is called ‘multiplier’. For example: 3 × 7 = 7 + 7 + 7 = 21.

Positive factors of 18 are 1,2,3,6,9, and 18. The factors set up 3 pairs of 18 (18*1, 2*9, 3*6), hence its product is 18^3, which is 5832.

So, the prime factorization of 18 is 18= 2 × 3 × 3. A factor tree is not unique for a given number. Instead of expressing 18 as 2 × 9, we can express 18 as 3 × 6.

Prime factorization: 51 = 3 x 17.

32 is an even number, and so it will have 2 as its factor. Only composite numbers can have more than two factors. Factors of 32 are 1, 2, 4, 8, 16, and 32….Factors of 32 in Pairs.

All factors of 32 are 1, 2, 4, 8, 16, and 32. Therefore, these are the common factors of 32.

Answer: nope . 32 is not a perfect square.

Why is 32 not a perfect square? Step 1: Answer: YES, 2 is in the list of numbers that are never perfect squares. The number 32 is NOT a perfect square and we can stop here as there is not need to complete the rest of the steps.

For 32, the answer is: No, 32 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 32) is as follows: 1, 2, 4, 8, 16, 32. For 32 to be a prime number, it would have been required that 32 has only two divisors, i.e., itself and 1.

A perfect number is an integer that equals the sum of its proper divisors. For example, 24 is abundant, its divisors giving a sum of 36; 32 is deficient, giving a sum…

20 is not a perfect square.

Is 41 a Composite Number? No, since 41 has only two factors, i.e. 1 and 41. In other words, 41 is not a composite number because 41 doesn’t have more than 2 factors.

42 is a composite number.

The number 69 is a composite number. Its factors are 1, 3, 23, and 69.

If the number has only two factors, 1 and itself, then it is prime. If the number has more than two factors, then it is composite.

In Mathematics, composite numbers are the numbers which have more than two factors, unlike prime numbers which have only two factors, i.e. 1 and the number itself. These numbers are also called composites….Prime Factorisation of Composite Numbers.

1 (one, also called unit, and unity) is a number and a numerical digit used to represent that number in numerals. It represents a single entity, the unit of counting or measurement.
