To simplify the expression ((7 - 3i)(-11 + 5i)), use the distributive property (FOIL method). First, multiply the real parts: (7 \cdot -11 = -77). Next, multiply the outer parts: (7 \cdot 5i = 35i), then the inner parts: (-3i \cdot -11 = 33i), and finally the last parts: (-3i \cdot 5i = -15i^2). Combine the results: (-77 + 35i + 33i + 15) (since (i^2 = -1)) simplifies to (-62 + 68i). Thus, the simplified expression is (-62 + 68i).

What is the answer to (7-3i plus 4 plus 8i)?
To simplify the expression ( (7 - 3i) + (4 + 8i) ), combine the real parts and the imaginary parts separately. The real parts are ( 7 + 4 = 11 ), and the imaginary parts are ( -3i + 8i = 5i ). Therefore, the answer is ( 11 + 5i ).

P and q are complex number's where p equals 2 plus 5i and q equals 6 minus i - find pq?
p = (2 + 5i)q = (6 - i)pq = (2 + 5i) (6 - i)pq = 12 + 30i - 2i - 5i2pq = 12 + 28i + 5pq = 17 + 28iIts the same as multiplying polynomials. Just multiply all the combinations of terms, group, and simplify.

What is the answer to (7-3i plus 4 plus 8i)?
To simplify the expression ( (7 - 3i) + (4 + 8i) ), combine the real parts and the imaginary parts separately. The real parts are ( 7 + 4 = 11 ), and the imaginary parts are ( -3i + 8i = 5i ). Therefore, the answer is ( 11 + 5i ).
What is 1 divided by 2 plus 5i in the form a plus bi?
1/(2 + 5i) (multiply both the numerator and the denominator by 2 - 5i)= 1(2 - 5i)/(2 + 5i)(2 - 5i)= (2 - 5i)/(4 - 25i2) (substitute -1 for i2)= (2 - 5i)/(4 + 25)= (2 - 5i)/29= 2/29 - (5/29)i
