Question

there are 2 columns 2 one 1st having 2 question and 2nd having 1st question

Answer 1

Answer:

the process by which green plants turn carbon dioxide and water into food using energy from sunlightLet. p/a + q/b + r/c =1. ……..(1)

a/p + b/q + c/r =0. ……. …. .(2)

Now squaring both sides of equation (1) , we get

[p/a + q/b + r/c]² = (1)²

=> (p/a)² + (q/b)² + (r/c)² + 2( pq/ab + qr/bc + pr/ac) = 1.

=> (p/a)² + (q/b)² +(r/c)² + 2[ pqr/abc ( c/r + a/p + b/q )] =1.

=> (p/a)² + (q/b)² + (r/c)² = 1. [ using equation (2)].
