  1. tan 40°×tan 50°×60
  2. tan 40°× cot(90-50) × tan 60
  3. tan 40°×cot 40°× tan 60°
  4. tan 40°×1/tan40°× tan 60°
  5. tan 60°= root 3

Answer:

1. tan40.tan50.tan60 = (1/cot40) x tan50 x tan60

                                  = [1/tan (90-40)] x tan50 x tan60

                                  = (1/tan50) x tan50 x tan60

                                  = 1 x tan60

                                  = tan60

                                  = √3
