In the multiplication sentence 3x5=15, the numbers 3 and 5 are known as factors. Factors are the numbers that are multiplied together to obtain a product. In this case, 3 and 5 are the factors that, when multiplied, result in the product of 15.
Here is one factor tree of 300: 300 20 x 15 (4x5) x (3x5) ((2x2)x5) x (3x5) You have reduced it to prime numbers, so you are finished. The factors of 300 are 2, 2, 3, 5, and 5.
4^3x5^2
4 = 4, and 4 = 2 x 2, so either a single prime number to the power 4-1 (23, 33, etc.), or two different prime numbers, each to the power 2-1, for example, 2x3, 2x5, 3x5, etc.
Any numbers that don't have common prime factors will do; for example, 23 and 32; 2x3 and 5x7, 3x5 and 2x7, etc.Any two consecutive numbers will have no common factor, for example, 8 and 9 (the first example I gave above), or 100 and 101. However, in the second example, 101 is not a composite number.

The generalisation is that multiplication is Abelian (or commutative) for numbers.
No, a 3x5 matrix cannot be multiplied by another 3x5 matrix. For matrix multiplication to be possible, the number of columns in the first matrix must equal the number of rows in the second matrix. Since a 3x5 matrix has 5 columns and the second 3x5 matrix has 3 rows, multiplication is not defined in this case.
Commutivity of multiplication or the commutative property of multiplication.
3x5=15 3 x5
The answer of a multiplication problem ex. 3x5=15 15 would be the product

3 x 7 = 3 x (5 + 2) And since multiplication is distributive over addition, 3 x (5 + 2) = 3 x 5 + 3 x 2
Bob had 3 crates. He had 5 calculus textbooks in each. How many calculus textbooks in all? 15 calculus textbooks.
Multiplication is done before addition, so it will be done before the plus. The result is:35 + 3 x 5 = 50
Divide the area of the windows by the area of the sheets. Note: 3x5 and 2x4 are not areas, they are numbers. And you don't say how big the sheets are, so it is difficult to be helpful.
A product is the result of multiplication, and a sum is the result of addition. Multiplication and addition are alike in that multiplication is really just repeated addition. For example, to multiply 3x5 is the same as 3+3+3+3+3 or 5+5+5. These will all result in either the product of 15 or the sum of 15.
1080 = 2^3x3^3x5 200= 2^3x5^2 LCM (1080,200) = 2^3x3^3x5^2 = 1800
