i think it might be ![\sqrt[5]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B3%7D)
but im not sure
Answer:
1. (i) 7, 21, 63, 189
(ii) 20, 10, 5, 2.5
2. (i) n²+n (where n = 1, 2, 3, ..)
(ii) 8/(10^n) (where n = 1, 2, 3, ..)
(iii) 1/(n+1) (where n = 1, 2, 3, ..)
First find the common factor of -30 and 75, which is 15.
Next find the common factors of the variables:
The factors of x$6 is x*x*x*x
Factor for y is y
Factors for Z^3 is z*z*z
Factors for Z^2 is z*z
The GCF would be x^4z^2
Final answer = 15x^4z^2
