Evaluate the following expresion: 2 (k3 + h - e) when h = 18, k = 2, and e = 7
To evaluate the expression: 2(k^3 + h - e) when h = 18, k = 2, and e = 7, substitute the given values into the expression and simplify.
First, substitute the values of h, k, and e:
2(2^3 + 18 - 7)
Perform the exponent operation first:
2(8 + 18 - 7)
Next, perform the addition and subtraction operations inside the parentheses:
2(26 - 7)
2(19)
Finally, multiply 2 by 19:
38
Therefore, the evaluated expression is 38.
To evaluate the expression 2(k^3 + h - e) when h = 18, k = 2, and e = 7, follow these steps:
Step 1: Replace the variables with their given values:
2(2^3 + 18 - 7)
Step 2: Simplify inside the parentheses:
2(8 + 18 - 7)
Step 3: Calculate the addition and subtraction inside the parentheses:
2(26 - 7)
Step 4: Calculate the remaining subtraction:
2(19)
Step 5: Calculate the multiplication:
2 * 19 = 38
So, the expression 2(k^3 + h - e) when h = 18, k = 2, and e = 7 evaluates to 38.
To evaluate the expression 2(k^3 + h - e) when h = 18, k = 2, and e = 7, you need to substitute the given values into the expression and perform the necessary calculations.
Step 1: Substitute the values of h, k, and e into the expression.
2(2^3 + 18 - 7)
Step 2: Simplify the expression within the parentheses first.
2(8 + 18 - 7)
Step 3: Perform the addition and subtraction operations inside the parentheses.
2(26 - 7)
2(19)
Step 4: Multiply 2 by 19.
38
Therefore, the value of the expression 2(k^3 + h - e) when h = 18, k = 2, and e = 7 is 38.
