hi ,
i got a question on complex no. How to prove the question is correct?
| (3 + j4)^5 | = 5^5
| ( 1 + j 3 ) | 2
i know that |Z| = |x + jy| = sqrt (x^2 + y^2) = ( Z x Z*)
for the lower part , i achieve ( 1 + 3 ) = 4 using ( Z x Z*) which i think i am right
but i am stuck on the upper part. can't acheive the answer..
(3 + j4)^5 which i can determine the r = 5 but am i on the right track converting into euler form ?
Thanks a lot for any help
Hi Chris0724
This should be : |Z| = |x + jy| = sqrt (x^2 + y^2) = sqrt ( Z x Z*)
Maybe you want to recalculate this one ^^for the lower part , i achieve ( 1 + 3 ) = 4 using ( Z x Z*) which i think i am right
Yes, r = 5 is right. You don't have to state it in euler form if you want to find |(3 + j4)^5|(3 + j4)^5 which i can determine the r = 5 but am i on the right track converting into euler form ?
But I don't think the question is right...
