It is not clear how far the scope of the square root extends: (√25)/4 = (√(5²))/4 = 5/4 = 1¼ = 1.25 √(25/4) - √(5²/4²) = (√(5²)) / (√(4²)) = 5/2 = 2½ = 2.5 I suspect you meant the latter, as in the "square root of all of 25 over 4".
sqrt(4/25) = 2/5
30. Square root is a number, times itself. 30x30 =900. Other examples of square root are 4x4=16, so 4 is the square root of 16. 5x5=25, so 5 is the square root of 25. 10 is the square root of 100, because 10x10=100.
The square root of 64/4 = 4
4x4=16, and 5x5=25, so 4 and 5 are the whole numbers closest to the square root of 19. [And incidentally of all the square roots of all the whole numbers between 16 and 25.]

a quarter is 1/4 and square root of 1/4 is square root (1/4)=square root of 1 divided by square root of 4 which is 1 divided by 2. So the answer is 1/2
(4 factorial divided by .4) minus (the square root of 4 divided by .4) or 44 divided by (the square root of 4 divided by .4)

(4 times 4 factorial + 4) divided by 4 4 factorial + the square root of 4 minus (4 divided by 4)
