I got (1/4)^10 but I got it wrong

(3^1/2)^3
_______ I got 1/216
9

(-56r^2)divide sign (-7r^2)= I got 8r

x(y)(x)(2y)

(12) (10xy^3) (3x^2y^2) (5x) (2y)

simplify sqaure root of 160000
simplify sqaure root of 0.04
simplify 3 * square root 81
simplify square root of 900

    ((1/4)^-3/(1/4)^2)^-2 =
    ((1/4)^-5)^-2 = (1/4)^10 = 9.54*10^-7

    (3^1/2)^3 = 3^(3/2) = 5.196.

    -56r^2/-7r^2 = 8.

    x*y*x*2y = 2X^2Y^2

    3600X^4Y^6.

    sqrt(16*10^4) = 4*10^2 = 400.
    sqrt means Square root.

    sqrt(0.04) = sqrt(4*10^-2) = 2*10^-1 =
    0.20

    3*sqrt(81) = 3*9 = 27

    sqrt(900) = sqrt(9*10^2) = 3*10 = 30

    sqrt(0.0025) = sqrt(25*10^-4) = 5*10^-2=
    0.05

    4^(-5/2) = 4^(-1/2)^)5 = 1/(4^(1/2)5 =
    1/sqrt(4)^5
