Grade 10 questions on how to use some important formuals to simplify radicals algebraic expressions with solutions are presented.

Solutions to the Above Problems The index of the radical 3 is odd and equal to the power of the radicand. since √x is a real number, x is positive and therefore |x| = x. is not a real number since -x^{2} - 1 is always negative. . The index 8 is even and equal to the power of the radicand. . . . The index 10 of the radical is even and equal to the power of the radicand. . The index 3 of the radical is odd and equal to the power of the radicand. . . Even index and power of radicand. Even index and power of radicand.
