Evaluate when a = 9, b = 6. a−b3 (1 point) Responses 3 3 6 6 1 1 9
When a = 9 and b = 6, the expression a−b^3 can be evaluated as follows:
9 - 6^3 = 9 - 6 * 6 * 6 = 9 - 216 = -207
So the correct response is -207
To evaluate the expression a−b^3 when a = 9 and b = 6, follow these steps:
Step 1: Substitute the values of a and b in the expression.
a−b^3 = 9 − 6^3
Step 2: Evaluate the exponent first.
6^3 = 6 × 6 × 6 = 216
Step 3: Substitute the value of the exponent back into the expression.
9 − 216
Step 4: Perform the subtraction.
9 − 216 = -207
Therefore, when a = 9 and b = 6, the value of the expression a−b^3 is -207.
To evaluate the expression a - b^3 when a = 9 and b = 6, you simply substitute the values of a and b into the expression and perform the necessary operations according to the order of operations (PEMDAS/BODMAS).
a - b^3
Substituting the values of a = 9 and b = 6:
9 - 6^3
Now, we need to perform the exponentiation first:
9 - 6^3
9 - 216
Continuing with the subtraction:
= -207
Therefore, when a = 9 and b = 6, the value of a - b^3 is -207.
