Question

What is the value of S[M(D(A(a, b), 2), D(A(a, b), 2)), M(D(S(a, b), 2), D(S(a, b), 2))]?

Options:

A . a² + b²

B . ab

C . a² – b²

D . a / b

Answer: Option B
:
B

Soln:(b)

S [M (D (A (a, b),2), D (A (a, b), 2)), M (D (S (a, b), 2), D (S (a, b), 2))]

S [M (D (a + b, 2), D (a + b, 2)), M (D (a – b, 2),D (a – b, 2))]

S [M(a + b)/2), (a + b) /2), M( )]

S [ (] = [(a +b)² – (a – b)² ]/ 2²
