Final answer:

To simplify the expression, we simplify the radicals and the fractions separately, and then combine like terms.

Step-by-step explanation:

To simplify the expression 8 - 4√18 / √50, we first simplify the radicals in the expression. √18 can be simplified to 3 √2, and √50 can be simplified to 5 √2. Therefore, the expression becomes: 8 - 4(3 √2) / 5 √2.

Next, we simplify the fractions. 4/5 cannot be simplified further, so the expression becomes: 8 - (12 √2) / (5 √2).

Finally, we combine like terms. We cannot combine 8 and 12 √2, so the simplified expression is: 8 - 12 √2 / 5 √2.
