Answer:
13/12
Step-by-step explanation:
2s - 1/4
s = 2/3
Plug s as 2/3 in the expression.
2(2/3) - 1/4
Multiply.
4/3 - 1/4
Find least common denominator.
(4 × 4)/(3 × 4) - (1 × 3)/(4 × 3)
16/12 - 3/12
Subtract fractions since denominators are same.
(16 - 3)/12
13/12
The value of the expression 2s - 1/4 when s = 2/3 is 13/12.

Answer:
For the given square root, two closest perfect square are are 0 and 1 and their square roots are 0 and 1 respectively.
Step-by-step explanation:

Hence, the two nearest square roots of the given square root are 0 and 1
For checking :

And, clearly 0.45 lies between 0 and 1
⇒ √0 < √0.2 < √1
⇒ 0 < 0.45 < 1
Hence, For the given square root, two closest perfect square are are 0 and 1 and their square roots are 0 and 1 respectively.
In the number 64,781, the value of the number 4 is 4,000. In the number 25,409, the value of the number 4 is 400.
That leaves you with 4,000 being 10 times greater than 400.
