Answer 1

Answer 18:-

As we know that sin(A + B) sin(A − B) =

sin² A - sin² B

LHS = sin A sin(60- A) sin(60 + A) =

sin A (sin² 60 - sin² A) = sin A (²₁ — sin²A) = 3 - 4 - =

3 sin A - 4 sin³ A 4 1 4 sin 3A = RHS

Answer 14:-

log3 (log₂ (x)) = 1

If loga (b) = c then b = a

⇒ log₂ (x) = 3¹

⇒ x = 23¹

..x = 8
