Solution

$(i) {(\frac{x^{a + b}}{x^{c}})}^{a - b} {(\frac{x^{b + c}}{x^{a}})}^{b - c} {(\frac{x^{c + a}}{x^{b}})}^{c - a} = (x^{a + b - c})^{a - b} . (x^{b + c - a})^{b - c} . (x^{c + a - b})^{c - a} = x^{(a - b) (a + b - c)} . x^{(b - c) (b + c - a)} . x^{(c - a) (c + a - b)} = x^{a^{2} - b^{2} - a c + b c} . x^{b^{2} - c^{2} - a b + a c} . x^{c^{2} - a^{2} - b c + a b} = x^{a^{2} - b^{2} - a c + b c + b^{2} - c^{2} - a b + a c + c^{2} - a^{2} - b c + a b} = x^{0} = 1$

$(i i) \sqrt[l m]{\frac{x^{l}}{x^{m}}} \times \sqrt[m n]{\frac{x^{m}}{x^{n}}} \times \sqrt[n l]{\frac{x^{n}}{x^{l}}} = (x^{l - m})^{\frac{1}{l m}} \times (x^{m - n})^{\frac{1}{m n}} \times (x^{n - l})^{\frac{1}{n l}} = x^{\frac{l - m}{l m}} . x^{\frac{m - n}{m n}} . x^{\frac{n - l}{n l}} = x^{\frac{l - m}{l m} + \frac{m - n}{m n} + \frac{n - l}{n l}} = x^{\frac{l n - m n + l m - l n + m n - l m}{l n m}} = x^{\frac{0}{l m n}} = x^{0} = 1$
