Evaluate when a = 9, b = 6. a−b3 (1 point) Responses 9 9 6 6 3 3 1
When a = 9 and b = 6, the expression a - b^3 evaluates to:
9 - 6^3 = 9 - 6 * 6 * 6 = 9 - 36 * 6 = 9 - 216 = -207
Therefore, the correct response is -207.
To evaluate the expression a - b^3 when a = 9 and b = 6, follow these steps:
1. Calculate b^3:
6^3 = 6 * 6 * 6 = 216
2. Subtract the value obtained in step 1 from a:
a - b^3 = 9 - 216 = -207
So, when a = 9 and b = 6, the value of a - b^3 is -207.
To evaluate the expression a−b^3 when a = 9 and b = 6, we can substitute the values of a and b into the expression and perform the necessary operations.
Step 1: Replace a with 9 and b with 6 in the expression:
9−6^3
Step 2: Simplify the exponent by raising 6 to the power of 3:
9−216
Step 3: Subtract 216 from 9:
-207
Therefore, the value of a−b^3 when a = 9 and b = 6 is -207.
