Calculate the amount lzl of the complex number
would glad if u guys could give me exemple because i cant find what lzl is
Yes, that is correct. So you now have:
We factor out the 7 from the denominator to help keep the computations simple.
So, multiply the complex fraction by the conjugate of the denominator:
This will cause the denominator to be real, and you will then have the complex number in rectangular form.
