tolong bantu dong no 3 dan 6

3. total pita=22²/₃ + 14⁵/₆ = 68/3 + 89/6
                                        = 136/6 + 89/6
                                        = 225/6
   dipotong sepanjang 3/4 meter, berapa buah pitanya?
   n = 225/6 ÷ 3/4 = 50  (B)

6. 2⁻³ × 2⁻⁴ = (1/2³)×(1/2⁴) = (1/8)×(1/16)= 1/128      (C)

semoga membantu..
