  1. Simplify the expression (4x4y−2z16x2y−1z−2)12\left(\frac{4x^4y^{-2}z}{16x^2y^{-1}z^{-2}}\right)^{\frac{1}{2}}.

    First, simplify the fraction inside the parentheses:

    4x4y−2z16x2y−1z−2\frac{4x^4y^{-2}z}{16x^2y^{-1}z^{-2}}

    Simplify the coefficients:

    416=14\frac{4}{16} = \frac{1}{4}

    Simplify the xx terms using the rule aman=am−n\frac{a^m}{a^n} = a^{m-n}:

    x4x2=x4−2=x2\frac{x^4}{x^2} = x^{4-2} = x^2

    Simplify the yy terms:

    y−2y−1=y−2−(−1)=y−2+1=y−1\frac{y^{-2}}{y^{-1}} = y^{-2 - (-1)} = y^{-2+1} = y^{-1}

    Simplify the zz terms:

    z1z−2=z1−(−2)=z1+2=z3\frac{z^1}{z^{-2}} = z^{1 - (-2)} = z^{1+2} = z^3

    Combine these simplified terms:

    14x2y−1z3=x2z34y\frac{1}{4} x^2 y^{-1} z^3 = \frac{x^2 z^3}{4y}

    Now, apply the exponent 12\frac{1}{2} to the entire simplified fraction. Remember that raising to the power of 12\frac{1}{2} is the same as taking the square root.

    (x2z34y)12=(x2)12(z3)12(4)12(y)12\left(\frac{x^2 z^3}{4y}\right)^{\frac{1}{2}} = \frac{(x^2)^{\frac{1}{2}} (z^3)^{\frac{1}{2}}}{(4)^{\frac{1}{2}} (y)^{\frac{1}{2}}}

    Apply the power to each term:

    (x2)12=x2×12=x1=x(x^2)^{\frac{1}{2}} = x^{2 \times \frac{1}{2}} = x^1 = x (z3)12=z32(z^3)^{\frac{1}{2}} = z^{\frac{3}{2}} (4)12=4=2(4)^{\frac{1}{2}} = \sqrt{4} = 2 (y)12=y(y)^{\frac{1}{2}} = \sqrt{y}

    Combine these results:

    xz322y\frac{x z^{\frac{3}{2}}}{2 \sqrt{y}} xz322y\boxed{\frac{x z^{\frac{3}{2}}}{2 \sqrt{y}}}
  2. Simplify −6x0+4x2+3x2-6x^0 + 4x^2 + 3x^2.

    Recall that any non-zero number raised to the power of 0 is 1, so x0=1x^0 = 1.
    Substitute x0=1x^0 = 1 into the expression:

    −6(1)+4x2+3x2-6(1) + 4x^2 + 3x^2 −6+4x2+3x2-6 + 4x^2 + 3x^2

    Combine the like terms (4x24x^2 and 3x23x^2):

    −6+(4+3)x2-6 + (4+3)x^2 −6+7x2-6 + 7x^2

    It is standard practice to write terms with higher powers first:

    7x2−67x^2 - 6 7x2−6\boxed{7x^2 - 6}
  3. Simplify, and write as an Index notation

    3×3×3×3×13×133 \times 3 \times 3 \times 3 \times \frac{1}{3} \times \frac{1}{3}.
    Group the terms:

    (3×3×3×3)×(13×13)(3 \times 3 \times 3 \times 3) \times \left(\frac{1}{3} \times \frac{1}{3}\right)

    Write the first group in index notation:

    3×3×3×3=343 \times 3 \times 3 \times 3 = 3^4

    Write the second group in index notation:

    13×13=(13)2\frac{1}{3} \times \frac{1}{3} = \left(\frac{1}{3}\right)^2

    Recall that 1an=a−n\frac{1}{a^n} = a^{-n}, so 13=3−1\frac{1}{3} = 3^{-1}.
    Therefore, (13)2=(3−1)2=3−1×2=3−2\left(\frac{1}{3}\right)^2 = (3^{-1})^2 = 3^{-1 \times 2} = 3^{-2}.
    Now multiply the two parts:

    34×3−23^4 \times 3^{-2}

    Use the rule am×an=am+na^m \times a^n = a^{m+n}:

    34+(−2)=34−2=323^{4 + (-2)} = 3^{4-2} = 3^2 32\boxed{3^2}
  4. Evaluate (1305)2\left(\frac{13^0}{5}\right)^2.

    Recall that any non-zero number raised to the power of 0 is 1, so 130=113^0 = 1.
    Substitute 130=113^0 = 1 into the expression:

    (15)2\left(\frac{1}{5}\right)^2

    Apply the exponent to both the numerator and the denominator:

    1252\frac{1^2}{5^2}

    Calculate the squares:

    1×15×5=125\frac{1 \times 1}{5 \times 5} = \frac{1}{25} 125\boxed{\frac{1}{25}}
