Remember
(√a)(√b)=√(ab)
and
so
![( \sqrt[5]{x^4})( \sqrt[5]{x^4} )](https://tex.z-dn.net/?f=%28%20%5Csqrt%5B5%5D%7Bx%5E4%7D%29%28%20%5Csqrt%5B5%5D%7Bx%5E4%7D%20%20%29)
=
![\sqrt[5]{(x^4)(x^4)}](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7B%28x%5E4%29%28x%5E4%29%7D)
4+4=8
![\sqrt[5]{x^8}](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7Bx%5E8%7D)
=
![( \sqrt[5]{x^5})( \sqrt[5]{x^3} )](https://tex.z-dn.net/?f=%28%20%5Csqrt%5B5%5D%7Bx%5E5%7D%29%28%20%5Csqrt%5B5%5D%7Bx%5E3%7D%20%20%29)
=
![x\sqrt[5]{x^3}](https://tex.z-dn.net/?f=x%5Csqrt%5B5%5D%7Bx%5E3%7D%20)
(√a)(√b)=√(ab)
and
so
4+4=8
-2-(+7) is the same thing at -2-7 which is -9
is the same thing as 
which is 
or 
Last but not least the last one is the Associative Property based on definition listed below :)
Associative Property:<span> When three or more numbers are added, the sum is the same regardless of the grouping of the addends. For example (2 + 3) + 4 = 2 + (3 + 4)</span>
