How do you simplify #sqrt(-32)#? Precalculus Complex Numbers in Trigonometric Form Complex Number Plane 1 Answer Carl S. Apr 5, 2018 #4isqrt2# Explanation: #i=sqrt{-1}# So #sqrt{-32}=isqrt{32}# #32 = 2 ^5# #sqrt{32} = 2 ^2.5= 2^2 times 2^ 0.5 = 4sqrt2# #sqrt{-32}=4isqrt2# Answer link Related questions What is the complex number plane?
