Question

Express the radical using the imaginary unit i

Answer 1

`\huge\boxed{\sf \pm 10i}`

Explanation:

Given radical:

`\pm √(-100)`

We can write it as:

`\pm √(-1 * 100) \\\\\pm √(-1) * √(100) \\\\\underline{We \ know \ that:}\ i =√(-1) \\\\\pm i * 10\\\\\boxed{\pm 10i}\\\\\rule[225]{225}{2}`
