Evaluate 3+jk+k^(3) when j=2 and k=6.

Identify given values and expression: Identify the given values and the expression to evaluate. We are given j = 2 and k = 6, and we need to evaluate the expression 3 + jk + k^3.Substitute given values into expression: Substitute the given values into the expression. Replace j with 2 and k with 6 in the expression 3 + jk + k^3 to get 3 + (2)(6) + 6^3.Perform multiplication: Perform the multiplication. Calculate 2 times 6 to get 12. So, the expression becomes 3 + 12 + 6^3.Calculate power of k: Calculate the power of k. Calculate 6^3, which is 6 multiplied by itself three times: 6 * 6 * 6 = 216. Now the expression is 3 + 12 + 216.Add numbers together: Add the numbers together. Add 3, 12, and 216 to get the final value of the expression. 3 + 12 + 216 = 15 + 216 = 231.

\newline

k=6

Identify given values and expression: Identify the given values and the expression to evaluate. $\newline$ We are given $j = 2$ and $k = 6$ , and we need to evaluate the expression $3 + jk + k^3$ .
Substitute given values into expression: Substitute the given values into the expression. Replace $j$ with $2$ and $k$ with $6$ in the expression $3 + jk + k^3$ to get $3 + (2)(6) + 6^3$ .
Perform multiplication: Perform the multiplication. $\newline$ Calculate $2 \times 6$ to get $12$ . $\newline$ So, the expression becomes $3 + 12 + 6^3$ .
Calculate power of $\newline$ $k$ : Calculate the power of $\newline$ $k$ . $\newline$ Calculate $\newline$ $6^3$ , which is $\newline$ $6$ multiplied by itself three times: $\newline$ $6 \times 6 \times 6 = 216$ . $\newline$ Now the expression is $\newline$ $3 + 12 + 216$ .
Add numbers together: Add the numbers together. $\newline$ Add $3$ , $12$ , and $216$ to get the final value of the expression. $\newline$ $3 + 12 + 216 = 15 + 216 = 231$ .
