Evaluate the expression when x = 8 and y = 9:
x(y − 9 exponent 3)
3 + 2
When x = 8 and y = 9, the expression "x(y − 9^3)" becomes "8(9 - 9^3)".
First, we need to calculate 9^3, which is equal to 729.
Next, substitute the value back into the original expression: 8(9 - 729).
Simplify the expression within the parentheses by subtracting 729 from 9: 8(-720).
Finally, multiply 8 with -720: -5760.
So when x = 8 and y = 9, the expression x(y − 9^3) evaluates to -5760.
The second expression is "3 + 2".
Adding these two numbers together gives us 5.
So when evaluated, the expression 3 + 2 equals 5.
