(c). (-1)^50 = 1

Answer 2

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: ANSWER \: \: } \mid}}}}}$

$\tt{(b) \: \: ( - 3) {}^{5} } \\ \\ \tt{ = ( - 3) {}^{2} \times ( - 3) {}^{3} } \\ \\ \tt{ = 9 \times ( - 27)} \\ \\ \tt{ = - 243} \\ \\ \\ \tt{(c) \: \: ( - 1) {}^{50} } \\ \\ \tt{ = \{ ( - 1) {}^{2} \} {}^{25} } \\ \\ \tt{ = (1) {}^{25} } \\ \\ \tt{= 1}$
