We are looking for a point on the number line that is on . Based on the number line provided, point G is the best representation of $\sqrt{49}$

Compare your answer with the correct one above

Question

Which point on the number line best represents $\sqrt{51}?$

Answer

To solve this problem, we can think of perfect squares around $\sqrt{51}$

$\sqrt{49}=7$

$\sqrt{64}=8$

This means that $\sqrt{51}$ has to be between and on the number line, but closer to because is closer to than . Based on the number line provided, point H is the best representation of $\sqrt{51}$

Compare your answer with the correct one above

Question

Which point on the number line best represents $\sqrt{60}?$

Answer

To solve this problem, we can think of perfect squares around $\sqrt{60}$

$\sqrt{49}=7$

$\sqrt{64}=8$

This means that $\sqrt{60}$ has to be between and on the number line, but closer to because is closer to than . Based on the number line provided, point I is the best representation of $\sqrt{60}$

Compare your answer with the correct one above
