3 sets of the 4 inch ribbon is 12,
10 sets of the 4 inch ribbon is 40
For this case we must find an expression equivalent to:
![\sqrt [4] {f}](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7Bf%7D)
By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So, rewriting the given expression we have:
