Answer 2

To Find :

• value of - 5i × 6i = ???

Sᴏʟᴜᴛɪᴏɴ :

$›› \sf \: - 5i \times 6i \\ \\ ›› \sf \: - 30 {i}^{2} ............(1)$

we know that, Value of :

• i = √-1
• i² = -1

Substituting value of i² in (1)

$›› \sf \: - 30 \times ( - 1)$

= 30

$\large\dag \large { \red{\underline{\bf{Hence }}}}$
