Answer:

\huge\boxed{\sqrt{72z^5}=6z^2\sqrt{2z}}

Step-by-step explanation:

72=(36)(2)=(6^2)(2)\\\\z^5=z^{2+2+1}=(z^2)(z^2)(z^1)\qquad\text{used}\ (a^n)(a^m)=a^{n+m}\\\\\sqrt{72z^5}=\sqrt{(6^2)(2)(z^2)(z^2)(z)}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\\sqrt{72z^5}=\sqrt{6^2}\cdot\sqrt{z^2}\cdot\sqrt{z^2}\cdot\sqrt{2z}\qquad\text{use}\ \sqrt{a^2}=a\ \text{for}\ a\geq0\\\\\sqrt{72z^5}=(6)(z)(z)\sqrt{2z}\\\\\sqrt{72z^5}=6z^2\sqrt{2z}

Find the markup and the selling price of the following item. Round answers to the nearest cent. A chemistry set costing $27.50,
postnew [5]

Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.

x=27.50\times\frac{32}{100}

x=27.50\times.32

x=8.8

Therefore, mark up price is $8.80.  

Since we know that selling price of any item equals the sum of cost and mark-up price of the item.

Let us find selling price of our chemistry set.  

\text{Selling price of chemistry set}=27.50+8.8

\text{Selling price of chemistry set}=36.30      

Therefore, the selling price of the chemistry set is $ 36.30.
