Final answer:
To solve the expression 50 : 25 + 1/5 * 5³, follow the order of operations and evaluate the exponent first, then perform multiplication, division, and addition in order.
Step-by-step explanation:
To solve the expression 50 : 25 + 1/5 * 5³, we need to follow the order of operations (PEMDAS/BODMAS). First, we evaluate the exponent 5³, which is equal to 5 * 5 * 5 = 125. Then, we multiply 1/5 and 125, which gives us 25. Next, we divide 50 by 25 to get 2. Finally, we add the result of the division to 25. Therefore, the expression evaluates to 27.
