A non-negative number is a number which is either zero or a positive number
For numerical example , to satisfy rule ![\sqrt[k]{a^{m} } =(\sqrt[k]{a} )^{m}](https://tex.z-dn.net/?f=%5Csqrt%5Bk%5D%7Ba%5E%7Bm%7D%20%7D%20%3D%28%5Csqrt%5Bk%5D%7Ba%7D%20%29%5E%7Bm%7D)
substitute a = 16, m = 2 and k = 2
The square root of a number is the number that we need to multiply by itself to get the original number
Now substituting, a = 16, m = 2 and k = 2 in given rule
![\sqrt[2]{16^{2} } =(\sqrt[2]{16} )^{2} \\\\\sqrt[2]{16*16}=\sqrt[2]{16}* \sqrt[2]{16}\\\\16=16](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%5E%7B2%7D%20%7D%20%3D%28%5Csqrt%5B2%5D%7B16%7D%20%29%5E%7B2%7D%20%5C%5C%5C%5C%5Csqrt%5B2%5D%7B16%2A16%7D%3D%5Csqrt%5B2%5D%7B16%7D%2A%20%20%5Csqrt%5B2%5D%7B16%7D%5C%5C%5C%5C16%3D16)
So, ![\sqrt[2]{16^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%5E%7B2%7D%20%7D)
satisfy the given rule.

Answer:
I'm pretty sure it's D
Step-by-step explanation:
....
The answer is <span>10 units
</span>
The diameter of the cylinder (d) is the twice of its radius (r): d = 2r
The volume (V) of the cylinder with radius r and height h is:
V = π r² h
We have:
d = 2r
r = ?
h = 7
π = 3.14
V = 175π
175π = π * r² * 7
175 = r² * 7
r² = 175/7
r² = 25
r = √25
r = 5
d = 2r
d = 2 * 5
d = 10
