Answer:
A. 4i[tex]\sqrt{5}[/tex]
Step-by-step explanation:
take the negative out of the radical symbol and replace it as i on the outside
[tex]i\sqrt{80}[/tex]
now we simplify the 80 with prime numbers until we cant simplify anymore
80/2=40
40/2=20
20/2=10
10/2=5
so we divided by 2 a total of four times and have a 5 left
since there is an imaginary 2 in the radical symbol we divide the amount of 2's (which is four) by 2
so there are two 2's outside the symbol
[tex]\\ 2 *2*i\sqrt{5}[/tex]
4i[tex]\sqrt{5}[/tex]
I hope this helps!
I know its confusing, but you can ask me any questions that you have.
