To evaluate the expression, we substitute the given values of a and b into the expression.
a - b^2/b = 10 - 2^2/2 = 10 - 4/2 = 10 - 2 = 8
Therefore, the answer is 8.
To evaluate the expression, substitute the values of a and b into the expression and solve:
a - b^2
= 10 - 2^2
= 10 - 4
= 6
Then, divide the result by b:
6 / 2
= 3
Therefore, the value of (a - b^2) / b when a = 10 and b = 2 is 3.
The correct answer is 3.
To evaluate the expression, follow these steps:
1. Substitute the values of a and b into the expression:
a - b^2 ÷ b = 10 - 2^2 ÷ 2
2. Simplify the expression inside the parentheses first:
2^2 = 4
3. Continue simplifying the expression:
10 - 4 ÷ 2 = 10 - 2 = 8
So, when a = 10 and b = 2, the expression a - b^2 ÷ b evaluates to 8. Therefore, the correct answer is 8.
