\(\sqrt{19}\approx4.359\), so (4.36) is the closest.

Step 3

Exam Tip

In approximation, first set the range using perfect squares. चरण 1: (16<19<25), इसलिए \(\sqrt{19}\) (4) और (5) के बीच है। चरण 2: \(\sqrt{19}\approx4.359\), इसलिए (4.36) सबसे निकट है। चरण 3: अनुमान में पहले पूर्ण वर्गों से सीमा तय करें।
