Question

If in matrix “A”, element "a_11=3", then in matrix “5A”, element "a_11=?"​

Answer 1

SOLUTION

GIVEN

$\sf{In \: matrix \: A \: the \: element \: \: a_{11} = 3}$

TO DETERMINE

$\sf{In \: matrix \: 5A \: the \: element \: \: a_{11} }$

CONCEPT TO BE IMPLEMENTED

Multiplication of matrix by a scalar

The product of a matrix A by a scalar k is a matrix whose each element is k times the corresponding elements of A

EVALUATION

Here it is given that

$\sf{In \: matrix \: A \: the \: element \: \: a_{11} = 3 }$

Now we know that , the product of a matrix A by a scalar k is a matrix whose each element is k times the corresponding elements of A

Here the scalar is 5

$\sf{In \: matrix \: 5A \: the \: element \: \: a_{11} }$

$= 5 \times 3$

$= 15$
