If `[(3/5,2/5),(a,b)]^2=I` then `(a,b)=`

If A=[(2 ,3,-5 ),(1, 2,-1)] and B=[(0, 5,1),(-2, 7, 3)] , find A+B and A-B

If A={:((-2,-1),(-5,-3)):}B={:((-3,1),(5,-2)):}and(AB)^(n)=I then n is (a/an)

If (5a - 3b) : (4a - 2b) = 2:3, then a:b is equal to: यदि (5a - 3b) : (4a - 2b) = 2:3 है, तो a : b का मान क्या होगा ?

If A = [(3,1),(5,2)] , and AB = BA = I, then find the matrix B.

If a:b=2:5 then (3a+4b):(4a+5b)=

If (a+b)-i(3a+2b)=5+2i, then find a and b.

Find the values of a and b, when: (i) (a+3,b-2)=(5,1) (ii) (a+b,2b-3)=(4,-5) (iii) ((a)/(3)+1,b-(1)/(3))=((5)/(3),(2)/(3)) (iv) (a-2,2b+1)=(b-1,a+2)
