PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!

Use the imaginary numberi to rewrite the expression as a complex number

Answer 1

i think the answer would be C

Explanation:

since it seemed you had to divide the numbers a hundred would turn into ten and ninety would turn into nine and because you have one negative and one positive that means it would have to be a negative so it would be

10 - 9i

Answer 2

Answer: B

Explanation:

`√(100) + √(-81)`

• 
  `√(100) = 10`
• 
  `√(-81) = √(-1) * √(81) = i * 9  = 9i`

`√(100) + √(-81)`

= 10 + 9i
