<h3>What is the simplification of power indices?</h3>
When we have indices in the form
, we are going to find the cube root of the (ax)². This can be mathematically expressed as:
![\mathbf{=(\sqrt[3]{ax})^2 }](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%28%5Csqrt%5B3%5D%7Bax%7D%29%5E2%20%7D)
From the given information:

![\mathbf{=(\sqrt[3]{8x^55y^3} } )^2](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%28%5Csqrt%5B3%5D%7B8x%5E55y%5E3%7D%20%7D%20%29%5E2)
![\mathbf{=(\sqrt[3]{40x^5y^3} } )^2](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%28%5Csqrt%5B3%5D%7B40x%5E5y%5E3%7D%20%7D%20%29%5E2)
![= (\sqrt[3]{40x^5} \times \sqrt[3]{y}^3)^2](https://tex.z-dn.net/?f=%3D%20%28%5Csqrt%5B3%5D%7B40x%5E5%7D%20%5Ctimes%20%20%5Csqrt%5B3%5D%7By%7D%5E3%29%5E2)

Answer:
2.9 miles
Step-by-step explanation:
If you draw this as a diagram, you will see that it is a right angled triangle and the missing side is the hypotenuse (the longest side). To calculate this, you will need to use the right angle law:

check out the document below (sorry, it's a little bit blurry)
800 + 16x = 720 + 21x. Cancel out the 720 to get 80 + 16x = 21x. Subtract 16x from both sides to get 80 = 5x. Divide by 5 to get 16 = x, or x = 16. 16 hours. The charge is 800 + 16(16), = 720 + 21(16) which = 800 + 256 = 720 + 336 which = 1,056 = 1,056. Hope this helped!
