1.If PPP is a 3×33\times 33×3 real matrix such that PT=aP+(a−1)IP^{T} = aP + (a-1)IPT=aP+(a−1)I, where a>1a > 1a>1, then:a.PPP is a singular matrixb.∣adj(P)∣>1|\text{adj}(P)| > 1∣adj(P)∣>1c.∣adj(P)∣=23|\text{adj}(P)| = 2\sqrt{3}∣adj(P)∣=23d.∣adj(P)∣=1|\text{adj}(P)| = 1∣adj(P)∣=1Login to continueOnly logged in users canattempt or see the solution.
