Estimate the square root to the nearest integer and tenth square root of 8

Answer:

√

8

≈

3

Explanation:

Note that:

2

=

4

<

8

<

9

=

3

2

Hence the (positive) square root of

8

is somewhere between

2

and

3

. Since

8

is much closer to

9

=

3

2

than

4

=

2

, we can deduce that the closest integer to the square root is

3

.

We can use this proximity of the square root of

8

to

3

to derive an efficient method for finding approximations.

Consider a quadratic with zeros

√

and

√

:

)

=

From this quadratic, we can define a sequence of integers recursively as follows:

The first few terms are:

0

,

1

,

6

,

35

,

204

,

1189

,

6930

,

...

The ratio between successive terms will tend very quickly towards

3

+

√

8

.

So:

√

≈

−

=

Taylor uses tape to mark a square play area in the basement for her daughter. The area measures 28 ft2. Is the side length of th

joja [24]

The side length of the square is a rational.

What is the area of the basement?

Any lower storey of a structure that is partially or completely below the lowest contiguous proposed ground level is referred to as a basement floor, provided that the portion of the storey above ground level does not exceed 75 cm.

Given: Taylor uses tape to mark a square play area in the basement for her daughter.

The area measures 28 ft2.

We know that the area of square is side length square.

As the area measures 28 square feet, so the side length of the square is, 28 feet.

Since 28 is a rational number.

Therefore, the side length of the square is a rational.
