Solution to

In case you had difficulty with the square roots given in Frame 5-28, the

Frame 5-30

problems are worked in greater detail below.

a. between 0.006

and 0.007

a.

0.00004

(actual square root is

0.0063245...)

(1) Pair off beginning at the decimal point

b. between 0.02 and

(2) 0.00004. = (00)(00)(40)

0.03

[You must add a zero to the end of the number so that

(actual square root is

the "4" is part of a pair.]

0.0215540...)

(3) Largest perfect square not over 40 is 36. The square root

of 36 is 6.

(4) (low)

(00)(00)(40) (0)(0)(6) 0.006

(5) (high)

(0)(0)(6+1) 0.007

b.

0.0004645775

(1) Pair off beginning at the decimal point

(2) 0004645775. = (00)(04)(64)(57)(75) (00)(04)

[The digits after the first non-zero pair of digits are

dropped.]

(3) Largest perfect square not over 04 is 4. The square root

of 4 is 2.

(4) (low)

(00)(04) (0)(2) 0.02

(5) (high)

(0)(2+1) 0.03
