Question

If a=b then a/2=b/2 pick the correct related statement​

Answer 1

Answer:

hey mate !! here is your answer...

Step-by-step explanation:

A scalar matrix is a square matrix in which all diagonal elements are equal and non-diagonal elements are zero.

An Identity matrix is a scalar matrix in which diagonal elements are 1.

∴ Every Identity matrix is a scalar matrix.

(A

T

)

T

=A

∴ Transpose of transpose of a matrix gives the matrix itself.

for every square matrix A there exists another matrix B such that AB=I=BA.

iff ∣A∣



=0

i.e iff A is invertible.

Hence, options B and C.
