Answer:

$(C)8x^4z^4\sqrt{2yz}$

Step-by-step explanation:

We want to determine an expression equivalent to: $\sqrt{128x^8y^3z^9}$

$\sqrt{ab} =\sqrt{a}*\sqrt{b}$

Therefore:

$\sqrt{128x^8y^3z^9}=\sqrt{128}*\sqrt{x^8}*\sqrt{y^3}*\sqrt{z^9}$

$=\sqrt{64*2}*\sqrt{x^{4*2}}*\sqrt{y^{2+1}}*\sqrt{z^{8+1}}\\=8\sqrt{2}*\sqrt{x^{4*2}}*\sqrt{y^2*y}*\sqrt{z^{8}*z}}$

$=8\sqrt{2}*x^4*y \sqrt{y}*z^4\sqrt{z}\\=8*x^4*z^4*\sqrt{2}*\sqrt{y}*\sqrt{z}\\=8x^4z^4\sqrt{2yz}$

If you're at a 75% in the class and get a 75% on the midterm, you will still have a 75% no matter how many points it's worth.
