The solution of the given expression \sqrt{7xy^7}\sqrt{21x^5y^5}will be 7x³y⁶√3.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The given expression will be solved as follows:-

E =  \sqrt{7xy^7}\sqrt{21x^5y^5}

E = \sqrt{7\times 7\times 3\times xy^7\times x^5y^5

E=\sqrt{7\times 7\times 3\times x^6y^{12}

E = 7x³y⁶√3.

Therefore the solution of the given expression \sqrt{7xy^7}\sqrt{21x^5y^5}will be 7x³y⁶√3.

Suppose that the cost of producing n pairs of shoes is given by the expression c(n)=30+5n. the average cost of producing a pair
makkiz [27]
<h3>Given</h3>

c(n)=30+5n\\a(n)=\dfrac{c(n)}{n}

<h3>Find</h3>

\dfrac{d}{dn}(a(n))\quad\text{at n=10}

<h3>Solution</h3>

\dfrac{d}{dn}(a(n))=\dfrac{d}{dn}\left(\dfrac{30+5n}{n}\right)=\dfrac{d}{dn}\left(30n^{-1}+5\right)\\\\=-30n^{-2}\\\\=-30\cdot 10^{-2}\qquad\text{at n=10}\\\\=-0.30

The derivative of the average cost function at n=10 is -0.30.
