√49/(72i)  (4+9i) is this like this? \[\sqrt{(\frac{ 49 }{ 72i })}(4+9i)?\]

mark_o.Best ResponseYou've already chosen the best response.1
or is it like this? \[\sqrt{\frac{ 49 }{ 72i }(4+9i)}?\]

mark_o.Best ResponseYou've already chosen the best response.1
ok the first one is \[\sqrt{\frac{ 49 }{ 72i }( \frac{ 7+2i }{ 7+2i })}(4+9i)\] \[\sqrt{\frac{ 49(7+2i) }{ 494i ^{2} }}(4+9i)\] \[\sqrt{\frac{ 49(7+2i) }{ 494(1) }}(4+9i)\] can you further simplify them ?

= sqrt[(34398i)/53](4+9i) =sqrt[6.4721.85i](4+9i)
