Answer:
(a):1/125
(b): -161051
(c):1/10000
Step-by-step explanation:
first the law of negative powers in indices which affects a and c
[tex]x^{ - m} = 1 \div \: x^{m} [/tex]
so using this law you can apply it to a and c which will be 1/5^3 and 1/(-100)^2 respectively but in be it is not affected by this law since the negative is included in the number to be raised so it's just the normal exponentiation but with a negative sighn
