Question

If I wanted to estimate the √99, the first step would be to find the two squares that 99 lies on the numberline. I could then think about the number 99 and how close it is to the smaller perfect square and the larger perfect square. That would tell me how far above or below the of the two perfect squares 99 lies on the numberline. I could then take the root of the perfect squares to see how I would estimate the square root of 99. The √99 is almost .

Answer 1

Answer:

Step-by-step explanation:

Smaller perfect squares near 99 is 81

Larger perfect square near 99 is 100

First step would be to find the two perfect squares that lies between on the number line. I could then think about the number 99 and how close it is to the smaller perfect square and the larger perfect square. That could tell me how far above or below the of the two perfect squares 99 lies on the number line. I could then take the square root of the perfect squares to see how I would estimate the square root of 99. The √99 is almost 10.

81 < 99 < 100

√81 < √99  < √100

8 < √99 < 10

So, √99 is almost 10.

Answer 2

Answer:

see explanation

Step-by-step explanation:

consider the perfect squares on either side of 99 , that is

81 < 99 < 100 , then

$\sqrt{81}$ < $\sqrt{99}$ < $\sqrt{100}$ , that is

9 < $\sqrt{99}$ < 10

now 99 is closer to 100 than it is to 81

then $\sqrt{99}$ is almost 10
