Let a = 3 – 5i and b = –1 + 7i. Which of the following are true statements? Check all that apply.ab = 38 + 16iab = 32 + 26i StartFraction a Over b EndFraction = negative StartFraction 19 minus 8 I Over 25 EndFraction ab = 2 + 2i StartFraction a Over b EndFraction = StartFraction 21 + 5 i Over 7 EndFraction StartFraction a Over b EndFraction = negative StartFraction 19 + 8 I Over 25 EndFraction
