Please simplify and explain to me how to do each of these. Greatly appreciated.

x = multiply sign (not a variable)

a)((9)^(1/2) (4)^2) / 24

b) (16)(2)^(x+2) The x here is a variable, not multiplication sign)

c) (3)^(-8)/ (3)^(-6) (3)^(-5)

d) ((4)^(-2) + (2)^(-4))^(-1)

Thank you so much if you can.

  • math -

    ((9)^(1/2) (4)^2) / 24
    (3 * 16)/24
    48/24
    2

    (16)(2)^(x+2)
    (2^4)(2^(x+2)
    2^(x+6)
    or
    64*2^x

    (3)^(-8)/ (3)^(-6) (3)^(-5)
    (3)^(-8)/ (3)^(-11)
    3^(-8-(-11))
    3^3
    27

    ((4)^(-2) + (2)^(-4))^(-1)
    (1/16 + 1/16)^(-1)
    (1/8)^(-1)
    8
