Question

Write \sqrt{-40}
−40
​
in simplest radical form.

Answer 1

Answer:

2*{2*i*√(10) - 20}

Step-by-step explanation:

i will interpret your expression as being

sqrt{-40}  − 40.  The first term factors to

sqrt{-4*10)

and the second stays as is.  

Then we have

sqrt(-4*10) - 40, or

i*2*sqrt(10) - 40, or

2*{2*i*sqrt(10) - 20}, or

2*{2*i*√(10) - 20}
