Answer 2

${i}^{39} + {i}^{ - 39} = 0$

because,

${i}^{2} = - 1$

${i}^{39} = { {i}^{2} }^{19} \times i = { - 1}^{19} \times i = - 1 \times i = - i$

${i}^{ - 39} = 1 \div {i}^{39}$

$1 \div {i}^{39} = 1 \div ( - i)$

$1 \div ( - i) \times - i \div - i$

$- i \div {i}^{2}$

$- i \div ( - 1) = i$

${i}^{39} + {i}^{ - 39} = - i + i = 0$
