Vedclass · Answer

(D) Let us evaluate each statement:$A$: The cube roots of unity are $1, \omega, \omega^2$. They form a Geometric Progression with common ratio $\omega$. Their sum is $1+\omega+\omega^2 = 0$. The statement says the sum is $1$,which is false. So,$A$ is $F$.$B$: $4+7 > 10$ is $11 > 10$ $(T)$. $2+8 $C$: $\exists x \in N$ such that $x^2-3x+2=0$. The roots are $x=1$ and $x=2$,both are in $N$. This part is $T$. $\exists n \in N$ such that $n$ is an odd number is $T$ (e.g.,$n=1$). $T \land T$ is $T$. So,$C$ is $T$.$D$: $3+i$ is a complex number $(T)$. $\sqrt{2}+\sqrt{3}=\sqrt{5}$ is false $(F)$. $T \lor F$ is $T$. So,$D$ is $T$.Therefore,both $C$ and $D$ have the truth value $T$.
