Explanation:
(a)
![5^(-3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/uehj1v419qv297rr3qwrxxcah90ctspgvq.png)
we can use property of exponent
![a^(-n)=(1)/(a^n)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2akbux28prddhditwp0q4aiy3r8t2enywp.png)
we get
![5^(-3)=(1)/(5^3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/30bgnai9euctnhknx87hic3t1v3nr58ur4.png)
![5^(-3)=(1)/(5* 5* 5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/cxkojb72f40wn2rodcx1ybe5n4o3wwjq9k.png)

(c)
![(-5^(-3))^(-1)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/exihtybh6unrzj9vv3phkmutaeod3iw4vk.png)
we can use property of exponent
![(a^(n))^m=a^(m* n)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/x4tuqhl8y1cxck99bmhcx0r37k9gqvcy14.png)
we get
![(-5^(-3))^(-1)=(-5)^(-3* -1)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/j13h9cidswtdgh5v7s5fbtetw4knpm0w1o.png)
![(-5^(-3))^(-1)=(-5)^3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/asbn3ndxvwhv0b7lc5xacfa4bdgnwsmdpa.png)
![(-5^(-3))^(-1)=(-5)* (-5)* (-5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8gb329nvxyizamstx424msq5vlpz0syik8.png)

(d)
![(-5^(-3))^(0)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bkpz051fv4vcydf3nlno47rid86ix5e9mv.png)
we can use property of exponent
![(a^(n))^m=a^(m* n)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/x4tuqhl8y1cxck99bmhcx0r37k9gqvcy14.png)
we get
![(-5^(-3))^(0)=(-5)^(-3* 0)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jt128gqlh4jwnutqdc3xf9i2bu3cjbg1e1.png)
