what is the answer of Ax is the same as AE


Sagot :

Answer:

AX is not the same as AE.

Step-by-step explanation:

Symbols and Variables:

Let

A be a matrix.

Let

X and

E be matrices or vectors of appropriate dimensions.

Understanding

AX:

AX represents the product of matrix

A and matrix/vector

X.

This product follows the rules of matrix multiplication, where the number of columns in

A must match the number of rows in

X.

Understanding

AE:

Similarly,

AE represents the product of matrix

A and matrix/vector

E.

This product follows the same rules of matrix multiplication, where the number of columns in

A must match the number of rows in

E.

Equating

AX and

AE:

For

AX to be the same as

AE,

X and

E must be identical.

This means that

=

X=E.

General Case:

Unless it is explicitly given that

X and

E are the same matrix/vector, we cannot assume

AX is the same as

AE.

Thus, AX is not the same as AE unless

=

X=E.
