Answer:

the square root of any negative number (a,b,d,e)

Step-by-step explanation:

i (imaginary number sign) is defined as the [tex]\sqrt{-1}[/tex] because you can't have a number multiplied by itself be a negative (-1 x -1 = +1) therefore the square root of any negative number is imaginary.

Answer: Option A, B, D, E

Step-by-step explanation:

By definition, imaginary numbers are all those that contain the square root of a negative number.

For example

[tex]\sqrt{-30}\\\\\sqrt{-1.25}\\\\[/tex]

Then identify among the options those numbers that contain the square root of a negative number

The options that meet these characteristics are (A, B, D, E)

[tex]\sqrt{-\frac{1}{2}}\\\\ \sqrt{-7}\\\\ \sqrt{-8}\\\\\sqrt{-\frac{5}{7}}[/tex]
