Answer:

7xy^{2} \sqrt[3]{2xy}

Step-by-step explanation:

\sqrt[3]{686x^{4} y^{7}}

686 = 343 * 2

x^{4} = x^{3} * x

y^{7} = y^{3} * y^{3} * y

\sqrt[3]{343} =7

\sqrt[3]{x^{3}} = x

\sqrt[3]{y^{3}* y^{3}} = y^{2}

so you're left with 2, x, and y inside the cube root, and 7, x, and y^2 outside

7xy^{2} \sqrt[3]{2xy}

Otto has some whipping cream that is 30%, butterfat, and some milk that is 2%, butterfat. He wants to make a 500 ML mixture of t
timofeeve [1]

The point J connote that the mixture has more than the expected volume and has the optimal butterfat percentage.

<h3>What is the point implying?</h3>

Note that in the question, it was supplied that  Otto intended to make a mixture of 12% butter fat.

Since:

Milk = 2% butter fat

Whipping cream = 30% butter fat.

This implies that  the milk contains the smallest of butter fat and it also implies that Otto would require  a lot more milk than cream, to be able to attain the 12% mixture.

This is known to be when point J is said to meet, and by using that data from point J, Otto require more of milk than the cream to get what he wants.

Therefore, The point J connote that the mixture has more than the expected volume and has the optimal butterfat percentage.
