સમાંતર બિંદુઓ (1,2,3) અને (9,8,5) થી સમાંતર દોરેલા વિમાનો દ્વારા સમાંતર પાઈપ્ડ રચાય છે...

5(5)/(6) -3(8)/(9) -? =1

Solve: (9-3y)/(1-9y)=8/5

A parallelopiped is formed by planes drawn through the points (1,2,3) and (9,8,5) parallel to the coordinate planes. Then which of the followIng is not the length of an edge of the rectangular parallelopiped (A) 2 (B) 4 (C) 6 (D) 8

A={1,2,3,4,5,6,7,8,9 B={ 2,4,6,8 } C={1,3,5 7,9} ( A cup (B cup C )) =_____.

If X={1,2,3,{4,5},6,{7,8,9,10} then {4,5} sub X

If A = {1,2,3……..9} , B = {2,4,6,7,8} and C = {3,4,5,8,9,10} then (A - B) uu C is .

Let A= {{1,2,3},{4,5} , {6,7,8,9}} . (i) {1,2,3} subA (ii) {{4,5}} subA .
