Pemdas, so exponent before multiply
so do a^-1/2 then multiply it by 2
remember that
![x^ \frac{m}{n}= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7Bm%7D%7Bn%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%20)
and
![x^{-m}= \frac{1}{x^m}](https://tex.z-dn.net/?f=x%5E%7B-m%7D%3D%20%5Cfrac%7B1%7D%7Bx%5Em%7D%20)
therefor,
![a^ \frac{-1}{2}= \frac{1}{a^ \frac{1}{2} } = \frac{1}{ \sqrt{a} }](https://tex.z-dn.net/?f=a%5E%20%5Cfrac%7B-1%7D%7B2%7D%3D%20%5Cfrac%7B1%7D%7Ba%5E%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%3D%20%5Cfrac%7B1%7D%7B%20%5Csqrt%7Ba%7D%20%7D%20%20)
the we multiply by 2
4.6, 6.41, 6.46
Hope this helps her!
Answer:
I think you have to multiple them all around the triangle
<h3>
Answer: Choice A</h3>
Side = 5 ft, side = 15 ft, side = 3 ft
Explanation:
The two sides 5 ft and 3 ft add to 5+3 = 8 ft which is not larger than the 15 ft side. This is exactly why a triangle is not possible here.
If we want a triangle to happen, then adding any two sides must be larger than the third side.
If we want a triangle with sides a,b,c, then we need the following to be true
Refer to the triangle inequality theorem for more information.
