√-49/(7-2i) - (4+9i) is this like this? \[\sqrt{(\frac{ -49 }{ 7-2i })}-(4+9i)?\]

or is it like this? \[\sqrt{\frac{ -49 }{ 7-2i }-(4+9i)}?\]

or is it like this? \[\sqrt{\frac{ -49 }{(7-2i)-(4+9i) }}\]?

which one now? the first, second or the third?
anonymous
  • anonymous
the former was correct ;)
anonymous
  • anonymous
the first one :)

ok the first one is \[\sqrt{\frac{ -49 }{ 7-2i }( \frac{ 7+2i }{ 7+2i })}-(4+9i)\] \[\sqrt{\frac{ -49(7+2i) }{ 49-4i ^{2} }}-(4+9i)\] \[\sqrt{\frac{ -49(7+2i) }{ 49-4(-1) }}-(4+9i)\] can you further simplify them ?

= sqrt[(-343-98i)/53]-(4+9i) =sqrt[-6.472-1.85i]-(4+9i)
