question :-

If p = 9 , find the value of :

\bold{1 \: ) \: 1 \:  -  \: p \:  +  \:  {p}^{2} }

\bold{2 \: ) \: 5 \:  {p}^{3}  \:  -  \: 9 \: p}

\bold{3 \: ) \:  {p}^{3} \:  -   \: 4 \: {p}^{2}  \:  +  \: p}

\bold{4 \: ) \: 8 \:   +  \: 6 \: p \:   -  \frac{1}{2}   \:  {p}^{2} }

Solution :-

  • Put the value of p = 9 in the equation .

\bold{1 \: ) \: 1 \:  -  \: p \:  +  \:  {p}^{2} }

\bold{: \longrightarrow \: 1 \:  -  \: 9\:  +  \: ( {9})^{2} }

\bold{: \longrightarrow \: 1 \:  -  \: 9\:  +  \: 81 }

\bold{: \longrightarrow \: 82 \:  -  \: 9 }

\bold{: \longrightarrow \: 73 }

\bold{2 \: ) \: 5 \:  {p}^{3}  \:  -  \: 9 \: p}

\bold{:  \longrightarrow \: 5 \: \times  ( {9})^{3}  \:  -  \: 9 \:  \times  \: 9}

\bold{:  \longrightarrow \: 5 \: \times   \: 729  \:  -  \: 81}

\bold{:  \longrightarrow \: 3645\:  -  \: 81}

\bold{:  \longrightarrow \: 3564}

\bold{3 \: ) \:  {p}^{3} \:  -   \: 4 \: {p}^{2}  \:  +  \: p}

\bold{:  \longrightarrow \:  ({9})^{3}  \:  -  \: 4 \:  \times  \: ( {9})^{2}  \:  +  \: 9}

\bold{:  \longrightarrow \:  729  \:  -  \: 4 \:  \times  \: 81 \:  +  \: 9}

\bold{:  \longrightarrow \:  729  \:  -   \: 324\:  +  \: 9}

\bold{:  \longrightarrow \:738 \:  -  \: 324 }

\bold{:  \longrightarrow \:414 }

\bold{4 \: ) \: 8 \:   +  \: 6 \: p \:   -  \frac{1}{2}   \:  {p}^{2} }

\bold{: \longrightarrow  \: 8 \:   +  \: 6 \:  \times  \: 9\:   -  \frac{1}{2}   \: \times  \:  ( {9})^{2} }

\bold{: \longrightarrow  \: 8 \:   +  \: 6 \:  \times  \: 9\: - \:\frac{1}{2}\: \times \: 81 }

\bold{: \longrightarrow  \: 8 \: + \: 54\:   - 1 \: \times  \: 40.5}

\bold{: \longrightarrow  \: 62\:   - \: 40.5}

\bold{: \longrightarrow  \: 21.5}
