" ( "[42." If "4b^(2)+(1)/(b^(2))=2" हो,तो "8b^(3)+(1)/(b^(3))" कामानहोगा:- "],[" () "0.5]

If (4b^(2)+(1)/(b^(2)))=2, then (8b^(3)+(1)/(b^(3)))=? (a) 0 (b) 1 (c) 2 (d) 5

(-8b^(2)+4b-8)+(-2b^(2)-5b-1)

What is (1)/(a-b) -(1)/(a+b) -(2b)/(a^(2)+b^(2))-(4b^(3))/(a^(4)+b^(4)) -(8b^(7))/(a^(8)-b^(8)) equal to ?

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

If A=[(2,-1),(4,2)] and B=[(2,3),(1,2)] find 2A+3B

For the matrices A and B, verify that (AB)'=B'A. (i) A=[{:(1),(3),(6):}],B=[2" "4," "5] (ii) A=[{:(5,3,-1),(2,0,4):}]B=[{:(-3,2),(2,1),(-1,0):}]

If A = [(1,3),(4,2)] , B = [(2,-1),(1,2)] , then |ABB'| =

If A= [[1,-1,0],[2,3,4],[0,1,2]] and B = [[2,2,-4],[-4,2,-4],[2,-1,5]] then, (A) A^(-1) =B (B) A^(-1) =6B (C) B^(-1) =B (D) B^(-1) = 1/6 A

If P(A)=(1)/(3)P(B) and P(A uu B)=0.5 when A, B are mutually exclusive events. Then P(A)= 1) (1)/(8) 2) (1)/(2) 3) (3)/(4) 4) (3)/(8)
