Question

find the conjugate of (1+i^3)-(4+3i^2)+(7-9i^4)​

Answer 1

Answer:

-2+i

Step-by-step explanation:

Given :- (1+i³) - (4+3i²) + (7-9i⁴)

We know that , i²= -1

i³ = -i

i⁴ = 1

Putting value .

=> (1-i ) - (4+3(-1) )+ (7-9(1))

=> 1-i -4 +3 + 7 -9

=> -2 -i

=> -(2+i)

=> z = -(2+i)

we know that , conjugate of (z) =x+iy = x-iy

since, conjugate of -(2+i ) = -(2-i) = -2+i Answer
