Explain how you could use a calculator to determine if √8 expressed as a decimal ever terminates.

• Use the square root button to find √8. Multiply that answer by itself. If the answer is 8, then it is a terminating decimal.

• Use the square root button to find √8. Multiply that answer by itself. If the answer is 8, then it is not a terminating decimal.

• None of them.
