The GCF is 5x because 5x goes into all the sets.
1. 343^(2/3)
3rdrt[(343(343)]
49
2. [2,197^(1/3)]^2
[3rdrt(2,197)]^2
169
3. 729^(2/3)
3rdrt[729(729)]
81
4. (1,000^2)^(1/3)
3rdrt(1,000^2)
100
5. [3rdrt(9261)]^2
441
6. [3rdrt(216^2)]
36
Hope this helps!
For this case we must write in algebraic symbology the expression described above:
We have an equation, then:
- x squared plus y squared:

- minus 2x plus 7y plus 1:

- equals zero:

We construct the equation:
