Question

can you guys plz help
simplify each expression x^-8, 1/x^-7 and 5/d^-3
( i'll give out a medal)

Answer 1

1. 1/x^8. When you put a number to a negative power, it can also be written as 1 over the number to the positive power.

2. x^7. Because of the rule I stated in the previous problem, it would make sense that the opposite would be the same.

3. d^3/5. Look at the above explanations!
