Question

Can someone help me solve this problem (i)-(7-8i)

Answer 1

I represents $\sqrt{-1}$ then there is the imaginary part, and the real part
the i is the imaginary
the 7 is the real part
distribute
i-(7-8i)
i-1(7-8i)
i-7+8i
-7+9i
it is normally writtnen in a+bi where a is the real part and b is the imaginary part

so the answer is -7+9i

Answer 2

(i) - (7 - 8i)
(0 + i) - (7 - 8i)
0 - 7 + i + 8i
-7 + 9i
