Radicals can look confusing when presented in a long string, as in \(\ 3+\sqrt{5}+\sqrt{7}+2+6 \sqrt{5}\). Means w/ Sequences, Finite geometric If the radicals are different, try simplifying first. Math is a way of solving problems by using numbers and equations. According to calculus, the index of a root radical can be ANY value (whole, decimal, fraction, irrational, positive, negative) other than zero. Since the radicals are the same, add the values in front of the radical symbols, and keep the radical.
