Answer:
1929
Explanation:
To evaluate the expression 9 + 8f5s when f=6 and s=8, we simply substitute those values into the expression in place of f and s:
9 + 8f5s = 9 + 8(6)5(8)
Using the order of operations (PEMDAS), we first multiply 6 and 8, then multiply the result by 5, and finally multiply the result by 8:
9 + 8f5s = 9 + 8(30)(8)
9 + 1920 = 1929
Therefore, when f=6 and s=8, the value of the expression 9 + 8f5s is 1929.
