How do you perform the operation and write the result in standard form given (-2+sqrt-8)+(5-sqrt-50)(−2+√−8)+(5−√−50)? Precalculus Complex Numbers in Trigonometric Form Complex Number Plane 1 Answer Shwetank Mauria Sep 16, 2016 (-1+sqrt(-8))+(5-sqrt(-50))=4-3sqrt2i(−1+√−8)+(5−√−50)=4−3√2i Explanation: (-1+sqrt(-8))+(5-sqrt(-50))(−1+√−8)+(5−√−50) = (-1+sqrt(-2xx2xx2))+(5-sqrt(-2xx5xx5))(−1+√−2×2×2)+(5−√−2×5×5) = -1+2sqrt2xxsqrt(-1)+5-5sqrt2xxsqrt(-1)−1+2√2×√−1+5−5√2×√−1 = -1+2sqrt2i+5-5sqrt2i−1+2√2i+5−5√2i = 4-3sqrt2i4−3√2i Answer link Related questions What is the complex number plane?
