urgent please answer..... 9i-9i√2
Update:ohh sorry can't really describe it
here's an example of what the answer must be
ex. √-25+√-9+√-4
=5i+3i+2i

Verified answer
√(-81)-4√(-32)+5√(-50)
=9i - 4√-16*2) + 5√(25 * 2)
=9i - 4* 4i√(2) + 5*5i√(2)
= 9i - 16i√(2) + 25i√(2)
=9i - 9i√(2) answer//
What do you want done with it???
The only thing I could do is factorise: 9(1-â2)i
Or perhaps convert to mod-arg form: 9â3 cis [-arctan (â2)]
there is no question?
the only thing you can do with that is simplify it
9i(1- sqrt(2))
Where is the question, exactly?
If your asking if the simplification was right... it is.
