- (b) Show that ii is real, even though i or 3i is not.arrow_forwardLet z = x(1 – i) + 8(-2+ i), where x is a real number. If z2 is a negative real number, what is the value of x? 10.arrow_forwardLet X and y be two real numbers different from zero. Simplifying the expression 2xy ( - x2y) + (2x2y)3 : (8x3y), we get: 1 2..3 (a) 2 - 2 1 (b) 3y 0 (c) 2xy 3 (d) - zx3y2 (e) zx2y 3 3arrow_forward
