Hal used the following procedure to find an estimate for Step 1: Since and and 81 < 82.5 < 100, is between 9 and 10. Step 2: Since 82.5 is closer to 81, square the tenths closer to 9. Step 3: Since 81.00 < 82.5 < 82.81, square the hundredths closer to 9.1. Step 4: Since 82.5 is closer to 82.62 than it is to 82.44, 9.09 is the best approximation for. In which step, if any, did Hal make an error? In step 1, is between 8 and 10 because 80 and. In step 2, he made a calculation error when squaring. In step 4, he made an error in determining which value is closer to 82.5. Hal did not make an error.
