Note that in the statement of the exercise are the values of j, k, and l. Then, to evaluate the given expression, we replace the given values of j, k, and l. So, we have:
[tex]\begin{gathered} j=9 \\ k=4.5 \\ l=3 \\ \mleft(j-2\mright)^3+k\text{ }\div l=(j-2)^3+\frac{k}{l} \\ \text{ We replace the know values} \\ (9-2)^3+\frac{4.5}{3}=7^3+1.5 \\ (9-2)^3+\frac{4.5}{3}=7\cdot7\cdot7+1.5 \\ (9-2)^3+\frac{4.5}{3}=343+1.5 \\ (9-2)^3+\frac{4.5}{3}=\boldsymbol{344.5} \end{gathered}[/tex]
Therefore, the result of evaluating the given expression is 344.5.
