Answer:

Step-by-step explanation:
We need to use the properties shown below to solve this:
1. ![\sqrt[n]{x^a} =x^{\frac{a}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Ea%7D%20%3Dx%5E%7B%5Cfrac%7Ba%7D%7Bn%7D%7D)
2. 
3. 
Area of a triangle is given by 1/2 * base * height, so we do that and simplify:

There are two sides (heads and tails). So one head would be 1/2, and one tail would also be 1/2.
Answer:
<h2>250%</h2>
Step-by-step explanation:
So first lets divide!
10÷4=2.5
Now, 2.5 x 100 = 250!
Hope this helped! Have a great day!

25% can be made in to 100% by multiplying it by 4.
Therefore, we can find the answer by multiplying 80 by 4.
80 * 4 = 320
