(6+3i)/(10+8i)

OpenStudy (ash2326):

@Marketaburn2 Do you want to simplify it?

OpenStudy (anonymous):

It says compute?

OpenStudy (alexwee123):

multiply the denominator and the numerator by the denominator's conjugate

OpenStudy (anonymous):

So multiply by 10-8i?

OpenStudy (ash2326):

We have \[\frac{6+3i}{10+8i}\] To compute this, multiply numerator and denominator by \[ \frac{(6+3i)(10-8i)}{(10+8i)(10-8i)}\] Can you find this?

OpenStudy (alexwee123):

yip on both numerator and denominator just like how you would retioonalize

OpenStudy (alexwee123):

rationalize*

OpenStudy (anonymous):

okay. @ash2326 I get that.
