Answer:
First option
is the correct answer.
Step-by-step explanation:
Let us consider each part, we have number 6 inside all the roots.
First we have to find cube root of 6.
![\sqrt[3]{6} =6^\frac{1}{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6%7D%20%3D6%5E%5Cfrac%7B1%7D%7B3%7D)
Now we have to find square root of this value.

So, first option
is the correct answer.
You can complete this by solving:

Which should give you .274418 or 27.44%
3 eggs for brownies, 2 eggs for cookies.
Because the total count went up 2 for one more batch of cookies, you know that 1C(ookies) = 2 eggs
3C = 6 eggs
15 - 6 = 9 eggs
3B(rownies) = 9 eggs
1B = 3 eggs
Try this solution:
