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

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

Best ResponseYou've already chosen the best response.1ok 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 ?
