`5/8-4/10=`

Find the sum: 5/8+3/(10) (ii) 4 3/4+9 2/5

Find the sum:  (i) 5/8+3/(10) (ii) 4 3/4+9 2/5

8(3)/(5)+1(2)/(5)-4(3)/(10)

|[2,3,7],[8,5,-4],[10,8,3]|=

|[2, 3, 7],[8,5,-4],[10,8,3]|= (A)242 (B)365 (C) 140 (D)0

|[2,3,7],[8,5,-4],[10,8,3]| = (A) 242 (B) 365 (C) 140 (D) Ο

If A=[[8,4],[10,5]],B=[[5,-4],[10,-8]] show that (A+B)^2=A^2+AB+B^2

Solve the matrix equation : 2x+{:[(-3,2,6),(5,-1,0),(3,-6,-2)]:}={:[(5,-8,-4),(1,3,10),(-5,8,0)]:} .

If A={2,3,5,8,10},B={3,4,10,12} and C={4,5,8,14} , then find each of the following : (i) (A cupB)cap(A cupC) (ii) (A capB)cup(A capC) .
