expand ( 5d-1) 4

  • Trigonometry -

    Do you mean (5d -1)^4 ?

    Square 5d -1 twice.

    The first squaring will give you
    25d^2 -10d +1

    Now square that. There will be more terms next time.

    This is not trigonometry

  • Trigonometry -

    Some people call the nth harmonic the nth ABOVE the fundamental and do not call the fundamental a harmonic. In that case, your answer would be 104/8 = 13 cm

    Whoops. Ignore last answer. I posted it in the wrong place
