I was having truouble figuring the 3rd and 4th roots out and answering them was tough when they were mixed.  I had an aha moment when Mrs. Burton said that the index was like little exponents for the coefficient.  When i saw that it got easier for me to do the roots.  I could just do the exponent then times them together.  This was good because i can do them faster and it helped me on the test a lot.  Now that we are headed to exponents i have some practice from the roots and mixed radicals.  I had the aha moment when  i was looking at a question the coefficient is just the answer to the original root times the other root.images
