\bf \sqrt{200y^4}\qquad 
\begin{cases}
200=2\cdot 2\cdot 2\cdot 5\cdot 5\\

y^4=y^{2+2}\\
\qquad y^2\cdot y^2\\
\qquad (y^2)^2
\end{cases}\implies \sqrt[2]{2^2\cdot 2\cdot 5^2\cdot (y^2)^2}

Please help me .....

Answer:

C - a stack of 15.6 watermelons

Step-by-step explanation:

Lets first go through each option:

<u>"A shopping receipt that totals $4.90"</u>:

This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.

<u>"A soccer game where the average score is 4.7"</u>:

This is also an appropriate result since it is the <em>average</em> score of a soccer game, so finding a decimal is appropriate.

<u>"A stack of 15.6 watermelons"</u>:

This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.

<u>"A classroom with 24 students"</u>:

This is an appropriate result since the number of students is a whole number not a decimal.

Hope this helps :)
