Answer 1

Answer:

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