    Next time use parantheses to clarify the question. This one is a little confusing but I will try my best.

    (21x^6)* (4 /x^4) * (5x^4 / 7)

    = ((21*4*5)(x^6 * x^4))/x^4

    = (420x^10)/x^4

    = 420x^6

    Hope this helps :)

    use ( and ) to denote the units... the way it is typed is confusing.

    (21 x^6) x 4 / (x^4)...

    ((21x^6) x 4) / (x^4)...

    please clarify and maybe someone can help...

    21x^6 x (4/x^4) x (5x^5/7)

    (84x^6/4x^4) x (5x^5/7)

    (420x^11/28x^4)

    15x^7
