Question

find multiplicative inverse of -5+4i and 1-i​

Answer 1

first we have to put by 1 it means -5+4i/1 and 1-i/1.

now multiplicative inverse of -5+4i/1 is 1/-5+4i but we should not put (-) in denominater so (-) will come up to nominater so the answer -1/5+4i

now multiplicative inverse of 1-i/1 is 1/1-i but we should not put (-) in denominater so (-) will come up to nominater so we get the answer as 1/1+i.

multipicative inverse is -1/5+4i and 1/1+i.

I hope that it was help to you please mark this answer as brilliant answer.
