Question

Question no 13, can someone tell me how to solve this one?

Answer 1

$we \: know \: that \: \:( {a}^{m} )^{n} = {a}^{m \times n} \\ \\ {a}^{m} \times {a}^{n} = {a}^{m + n} \\ by \: using \: these \: two \: formulae \\ \\ {x}^{( \frac{1}{a - b} ) \times ( \frac{1}{a - c}) } \times {x}^{( \frac{1}{b - c}) \times ( \frac{ - 1}{a - b} )} \times {x}^{( \frac{ - 1}{a - c}) \times (\frac{ - 1}{b - c} )} \\ \\ {x}^{ \frac{ b - c - a + c + a - b}{(a - b) \times (a - c) \times (b - c)} } \\ \\ {x}^{0} = 1$
