Question

Please help me answer this problem

Answer 1

answer

$\sqrt{11} - \sqrt{31}$i

explanation

note that i = $\sqrt{-1}$ and that $\sqrt{ab} =\sqrt{a} *\sqrt{b}$

$\sqrt{11} - \sqrt{-31}$

= $\sqrt{11} - \sqrt{31 * -1}$

= $\sqrt{11} - \sqrt{31}*\sqrt{-1}$

= $\sqrt{11} - \sqrt{31}$i

note that the i is outside of the square root

Answer 2

Square root symbol 11 - i square root symbol 31
