Please Simplify:
(root5 a^7/2)^4 a^3/a^8

I am having a hard time figuring where to start on this problem. Can someone please help me?

  • Math - ,

    (sqrt5)^4=25
    (a^7/2)^4=(a^3.5)^4=a^14
    a^14 *a^3*a^-8=a^9

    check my thinking.

  • Math - ,

    Not too sure if that is correct. This is what I got.

    = (sqrt (5)4*(a (7/2)) 4) a3-8
    =5(1/2)*4*a (7/2)*4*a3-8
    =25 a14 a-5
    =25 a9

    Is this correct?
