12th root of 8^x = (12th root of 8)^x
![\sqrt[12]{8^{x}} = \left(\sqrt[12]{8}\right)^{x}](https://tex.z-dn.net/?f=%5Csqrt%5B12%5D%7B8%5E%7Bx%7D%7D%20%3D%20%5Cleft%28%5Csqrt%5B12%5D%7B8%7D%5Cright%29%5E%7Bx%7D)
=========================================
Explanation:
The general rule is
![\sqrt[n]{x} = x^{1/n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D%20%3D%20x%5E%7B1%2Fn%7D)
so any nth root is the same as having a fractional exponent 1/n.
Using that rule we can say the cube root of 8 is equivalent to 8^(1/3)
![\sqrt[3]{8} = 8^{1/3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%20%3D%208%5E%7B1%2F3%7D)

Raising this to the power of (1/4)x will have us multiply the exponents of 1/3 and (1/4)x like so
(1/3)*(1/4)x = (1/12)x
In other words,
![\left(8^{1/3}\right)^{(1/4)x} = 8^{(1/3)*(1/4)x}](https://tex.z-dn.net/?f=%5Cleft%288%5E%7B1%2F3%7D%5Cright%29%5E%7B%281%2F4%29x%7D%20%3D%208%5E%7B%281%2F3%29%2A%281%2F4%29x%7D)
![\left(8^{1/3}\right)^{(1/4)x} = 8^{(1/12)x}](https://tex.z-dn.net/?f=%5Cleft%288%5E%7B1%2F3%7D%5Cright%29%5E%7B%281%2F4%29x%7D%20%3D%208%5E%7B%281%2F12%29x%7D)

From here, we rewrite the fractional exponent 1/12 as a 12th root. which leads us to this
![8^{(1/12)x} = \sqrt[12]{8^{x}}](https://tex.z-dn.net/?f=8%5E%7B%281%2F12%29x%7D%20%3D%20%5Csqrt%5B12%5D%7B8%5E%7Bx%7D%7D%20)
![8^{(1/12)x} = \left(\sqrt[12]{8}\right)^{x}](https://tex.z-dn.net/?f=8%5E%7B%281%2F12%29x%7D%20%3D%20%5Cleft%28%5Csqrt%5B12%5D%7B8%7D%5Cright%29%5E%7Bx%7D%20)
Answer:
8.3 meters
Step-by-step explanation:
58.1 / 7 =8.3
Answer:
1/8 and 2/6 put them in common terms making it
3/24 and 8/24 so you add them giving you
11/24 which can't be simplified so she used 11/24 of a gallon of pain in total
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
x equals 4 when y equals 9 on that line
N would equal 28 since 60-32 is 28
