`((4i^3-i)/(2i+1))^2`can be expressed in `a +ib` as (A) `3+4i` (B) `3-4i` (C) `4+3i` (D) `4-3i`

((4i^3-i)/(2i+1))^2 can be expressed in a+i b as 3+4i b. 3-4i c. 4+3i d. 4-3i

((4i^(3)-i)/(2i+1))^(2) can be expressed in a+ib as 3+4i b.3-4i c.4+3i d.4-3i

Simplify: [1 / (1 - 2i) + 3 / (1 + i)] [(3 + 4i) / (2 - 4i)]

i+ 2i^(2) + 3i^(3) + 4i^(4) + …. + 100i^(100) =

Answer the following. Simplify the following an express in the form a + ib: (5 + 7i) / (4 + 3i) + (5 +7i) / (4 - 3i)

Express (3- 2i)/(5 + 4i) + (3 + 2i)/(5 - 4i) in the form of a + ib

Express the following in the form a + ib (4 + 3i)/((2+3i)(4-3i))
