Question

Suppose p,q and r are matrices having order 3*5 ,a*b ,c*d then the value of ac+bd if matrix 2p+3q-4R

Answer 1

Step-by-step explanation:

In question sum of matrixes is defined it means order of all matrix should be equal to 3*5

Here vale of a=3 b=5and c=5

so value of ac+bd= 3*3+5*5 = 9 + 25= 36

Answer 2

Step-by-step explanation:

See in the picture as addition and subtraction is defined so the order of all matrices will be same

ac+bd=3(3)+5(5)

=34 is the answer
