8.1 Radical Expressions & Functions The number  c  is a   square root of  a  if  c 2  = a .  The principal square root of a nonnegative number is its  nonnegative square root.  The radical sign is used to indicate the principal square root of the number over  which it appears. For each number find all of its square roots: 1. 64 2. 169 3. 3600 4. 256 Simplify: 5. 196 6. 289 - 7. 49 121 - 8. 0025 . Identify the radicand, the root index, and the coefficient: 9. 2 3 5 b - - 10. 3 16 5 81 11. 2 3 6 3 ( ) x y x x y - Find the specified value of each function if it exists: 12.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
