4n ^ 3 * (n + m) - 7 for n = 2 , m = - 5
To find the value of the expression 4n^3 * (n + m) - 7 when n = 2 and m = -5, we substitute the given values into the expression and perform the calculations step by step.
Starting with the expression:
4n^3 * (n + m) - 7
Substituting n = 2 and m = -5:
4(2)^3 * (2 + (-5)) - 7
Simplifying inside the parentheses first:
4(2)^3 * (-3) - 7
Evaluating the exponent:
4(8) * (-3) - 7
Performing the multiplication:
32 * (-3) - 7
Evaluating the products:
-96 - 7
Calculating the subtraction:
-103
Therefore, when n = 2 and m = -5, the expression 4n^3 * (n + m) - 7 has a value of -103.
To evaluate the expression 4n^3 * (n + m) - 7 with n = 2 and m = -5, follow the steps below:
Step 1: Replace n with 2 and m with -5 in the expression:
4 * (2)^3 * (2 + (-5)) - 7
Step 2: Simplify the parentheses:
4 * (8) * (-3) - 7
Step 3: Calculate the exponent:
4 * 8 * (-3) - 7
Step 4: Perform the multiplication and subtraction:
-96 - 7
Step 5: Simplify the expression:
-103
Therefore, when n = 2 and m = -5, the value of the expression 4n^3 * (n + m) - 7 is -103.
To find the value of the expression 4n^3 * (n + m) - 7 for n = 2 and m = -5, we can substitute the given values into the expression and compute the result step by step.
Step 1: Substitute n = 2 and m = -5 into the expression:
4(2)^3 * (2 + (-5)) - 7
Step 2: Simplify the expression inside the parentheses:
4(8) * (2 + (-5)) - 7
Step 3: Perform the addition inside the parentheses:
4(8) * (-3) - 7
Step 4: Multiply 4 by 8:
32 * (-3) - 7
Step 5: Perform the multiplication:
-96 - 7
Step 6: Subtract 7 from -96:
-103
Therefore, the value of the expression 4n^3 * (n + m) - 7 when n = 2 and m = -5 is -103.
