\sin ^{-1} x+\sin ^{-1} y=\pi

and, if

x=\lambda y

, then the value of

39^{2 \lambda}+5^2

must be:

View answer and explanation

Correct option: B

1546

Option B (1546) is correct because from the given condition, we find that

x=y

, so

\lambda = 1

, and then calculate

39^{2\lambda} + 5^2 = 39^2 + 25 = 1521 + 25 = 1546
