A non-negative number is a number which is either zero or a positive number
For numerical example , to satisfy rule [tex]\sqrt[k]{a^{m} } =(\sqrt[k]{a} )^{m}[/tex] 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
[tex]\sqrt[2]{16^{2} } =(\sqrt[2]{16} )^{2} \\\\\sqrt[2]{16*16}=\sqrt[2]{16}* \sqrt[2]{16}\\\\16=16[/tex]
So, [tex]\sqrt[2]{16^{2} }[/tex] satisfy the given rule.
