\textbf{Concept:}

\text{Remainder theorem:}

\text{The remainer when P(x) is divided by (ax-b) is $P(\frac{b}{a})$}

\textbf{Given:}

\text{P(x)=}3x^3-6x^2+3x-7

\text{The remainer when P(x) is divided by (3x-4) is $P(\frac{4}{3})$}

P(\frac{4}{3})

=3(\frac{4}{3})^3-6(\frac{4}{3})^2+3(\frac{4}{3})-7

=3(\frac{64}{27})-6(\frac{16}{9})+3(4)-7

=\frac{64}{9}-2(\frac{16}{3})+5

=\frac{64}{9}-\frac{32}{3}+5

=\frac{64-96+45}{9}

=\frac{13}{9}

\therefore\textbf{The remainer when P(x) is divided by (3x-4) is $\bf\frac{13}{9}$}
