Question

Somebody help me solve what is in the image

Answer 1

Answer:

√2 is approximately 1.4.

Step-by-step explanation:

Part E:

1.3 squared is 1.69.

1.4 squared is 1.96.

1.5 squared is 2.25.

√2 is not between 1.3 and 1.4 because 1.4 squared only reaches up to 1.96 and not 2.

√2 is between 1.4 and 1.5 because 1.4 squared is 1.96 while 1.5 squared is 2.25. The √2 will be somewhere between 1.4 between 1.5.

2 is closer to 1.96 (0.04 units) than 2.25 (0.25 units). Thus, √2 is approximately 1.4.
