Henry calculated the distance from the origin to the point
(8,3, -1). His work is shown below.
Analyze Henry's work. Is he correct? Explain your answer.
Step 1: d = V(8)2 + (3)2 + (-1)2
No, he did not substitute properly in step 1
No, he incorrectly evaluated an exponent in step 2.
No, he did not add correctly in step 3
Yes, he calculated the distance correctly
Step 2: d = 764 + 9 +2
O
Step 3: d = 775
Step 4: d = 53
