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:
Formula for mean in grouped data
= Zfx/ Zf
f = sum of the number of mice
= 35
Frequency = 39 + x
Mean = 7
Fx = 20 + 78 + 112 + 8x + 54
= 264 + 8x
7 = 264 + 8x/ 39 + x
7(39+x) = 264 + 8x
After solving you will get
x = 9
Hope this helps.
Yeah i cant see them either
