Which of the following satisfies the identity property of multiplication? => 1 × 1 = 1 or 1 - 1 = 0 or 1 + 1 = 2 or 1 × 0 = 0..

Which of the following equations represent the identity property of multiplication? => ab + 0 = ab or a ( b + c ) = ab + ac or abc x 1 = abc or None of the above..

). If A be a matrix of the order m x n and B be a matrix of the order n x q, then A and B can be multiplied and the product will be a matrix of order m x q. then Elements of rows of matrix A are multiplied by the corresponding elements of columns of B and we get AB. = [5 x 3 + 6..

Choose the number sentence that correctly shows the use of the identity property of multiplication. => 8 + 1 = 9 or 8 + 0 = 8 or 8 × 1 = 8 or 8 × 0 = 0..

A square matrix A=[a i j ] n x n is called an identity or unit matrix if (2) a i j =1 for all i = j In other words a square matrix each of whose diagonal elements is unity and each of whose non-diagonal elements is equal to zero is called an identity..

Mary knows that identity element for addition is 0. Which of the following is the correct number sentence? => 15 + 51 = 0 or 15 + 15 = 0 or 15 + 1 = 0 or 15 + 0 = 15..

Let A be a matrix of order mxn. Let B be a matrix of order nxp. Then the product of the matrices A and B is of order mxp. i.e., when we multiply two matrices the number of columns of the first matrix should be equal to the number of rows of the second matrix. Two matrices can be multiplied by usin..

In lithium (Z =3), the third electron goes to the next 2s orbital. In Beryllium (Z = 4), the fourth electron fills 2s orbital and in boron (Z = 5), the next electron goes to the next available 2p orbital. In carbon, the sixth electron is also to go into the 2p orbital as 2p subshell can accom..
