Question 372427: Exponents and Radicals. Simplify. Remember to use absolute-value notation when necessary. If a root cannot be simplified, state this.
- ^4√625
*** "^" means to the fourth power.***
I have no idea as to what I'm doing here. Can someone please explain?

Since 5%5E4=625, we can say that -root%284%2C625%29=-root%284%2C5%5E4%29=-5 using the idea that root%28n%2Cx%5En%29=abs%28x%29 (note: since 5 is positive, we don't have to worry about the absolute value).


So -root%284%2C625%29=-5
