See a solution process below:

Explanation:

We can rewrite the number 89 as:

89 = 80 + 989=80+9

We then rewrite the expression in the problem as:

5 xx (80 + 9)5×(80+9) or 5(80 + 9)5(80+9)

Using the distributive property we can rewrite and evaluate the expression as:

(5 xx 80) + (5 xx 9) =>(5×80)+(5×9)

400 + 45 =>400+45
