plz put brackets after each expression so that ur ques get clear to me

2. InsanelyChaotic

ok koala ;0

3. mark_o.

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

4. mark_o.

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

5. InsanelyChaotic

yes!!! :))

6. mark_o.

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

7. mark_o.

which one now? the first, second or the third?

8. InsanelyChaotic

the former was correct ;)

9. InsanelyChaotic

the first one :)

10. mark_o.

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 ?

11. InsanelyChaotic

No

12. mark_o.

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

13. mark_o.

ok i think we cant simplify them any more :D

14. InsanelyChaotic

thank you kind sir!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11111

15. mark_o.

ok YW have fun now and good luck ... :D
