1.	If in matrix “A”, element "a_11=3", then in matrix “5A”, element "a_11=?"
Answer» SOLUTION GIVEN $\sf{In \: <klux>MATRIX</klux> \: A \: the \: element \: \: a_{11} = 3}$ 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 $\sf{In \: matrix \: 5A \: the \: element \: \: a_{11} }$ $= 5 \times 3$ $= 15$ ━━━━━━━━━━━━━━━━ Learn more from Brainly :- 1.
