Vedclass · Answer

(A) To estimate the value,we round the numbers to the nearest perfect squares:$\sqrt{624} \approx \sqrt{625} = 25$$\sqrt{63} \approx \sqrt{64} = 8$$\sqrt{398} \approx \sqrt{400} = 20$$\sqrt{17} \approx \sqrt{16} = 4$Now,substitute these values into the expression:$25 	imes 8 + 20 \div 4$Using the order of operations $(BODMAS)$:$= 200 + 5 = 205$

Estimate the value of $\sqrt{624} \times \sqrt{63} + \sqrt{398} \div \sqrt{17} = ?$
