joshoyen
  • joshoyen
for |-10+6i|
Er.Mohd.AMIR
  • Er.Mohd.AMIR
oh sqrt{(10)^2+(6)^2}=sqrt(100+36)=sqrt(136)=sqrt(2*2*34)=2 sqrt(34) is ans

  • joshoyen
couldn't you simplifity it more? to make it 2 sqrt 17 ?
Er.Mohd.AMIR
  • Er.Mohd.AMIR
fine

  • joshoyen
that was it, but couldn't you simplifity it evne more?
joshoyen
  • joshoyen
2 sqrt 34 to 2 sqrt 17
Er.Mohd.AMIR
  • Er.Mohd.AMIR
no sqrt(x*x)=x if two number are same in sqrt one come out only
joshoyen
  • joshoyen
hmmm, i still don't get it
joshoyen
  • joshoyen
if which two numbers are the same?
Er.Mohd.AMIR
  • Er.Mohd.AMIR
sqrt(136)=sqrt(2*2*34)=2 sqrt(34) s number two is same so out it 34=2*17 no number is same
Er.Mohd.AMIR
  • Er.Mohd.AMIR
off
