Final answer:
To evaluate and write in simplest form, substitute the given values for x and y in the expression y and evaluate. In this case, x = 8 and y = 10, so the value of the expression is 10.
Step-by-step explanation:
To evaluate and write in simplest form, substitute the given values for x and y in the expression y. In this case, x = 8 and y = 10. Therefore, the expression becomes 10. Hence, when x = 8 and y = 10, the value is 10.
