व्याख्या कीजिए -
`L + L = L, `

Justify L + L = L and L - L = L.

Construct square LMNO, such that l (LM) = l (LO) = 6 cm, l (ON) = l (NM) = 4.5 cm, l (OM) = 7.5 cm,

L-6 to L-9

Justify L + L = L and L-L =L

Five balls L1, L2, L3, L4 and L5 are kept one above the other (not necessarily in the same order). L1 is just above L5 and just below L4. L2 is just above L3 and just below L5. How many balls are above L2? पांच गेंदों L1, L2, L3, L4 और L5 को एक के ऊपर एक रखा जाता है (जरूरी नहीं कि उसी क्रम में)। L1, L5 के ठीक ऊपर और L4 के ठीक नीचे है। L2, L3 के ठीक ऊपर और L5 के ठीक नीचे है। L2 के ऊपर कितनी गेंदें हैं?

In figure, sides L M and L N of L M N are extended to P and Q respectively. If x > y , show that L M > L N .

L-9 to L-11

The stability of +1 oxidation state in aqueous solution is in the order- A l I n > T l T l > In > G a > A l A l > T l > G a > In T l > A l > G a > In

Let L be the set of all lines in a plane and R be the relation in L defined as R = {(L _(1), L _(2)) : L _(1) is perpendicular to L _(2) }. Show that R is symmetric but neither reflexive nor transitive.
