Answer: ![\frac{8}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B5%7D)
Step-by-step explanation:
343 is equal to 7 to the power of 3.
49 is equal to 7 to the power of 2.
You can then make the equation:
![(7^{3})^x = (7^2)^{4-x}](https://tex.z-dn.net/?f=%287%5E%7B3%7D%29%5Ex%20%3D%20%287%5E2%29%5E%7B4-x%7D)
The powers law means if something is to the power of something, it is multiplied.
So, we can remove the 7 and make the equation:
3x = 2(4-x)
3x = 8 - 2x
5x = 8
x = ![\frac{8}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B5%7D)
You can verify this by plugging it in,
![343^{8/5} = 11388.6066](https://tex.z-dn.net/?f=343%5E%7B8%2F5%7D%20%3D%2011388.6066)
![49^{4-(8/5)} = 11388.6066](https://tex.z-dn.net/?f=49%5E%7B4-%288%2F5%29%7D%20%3D%2011388.6066)
