sqrt(6.25) = 2.5 There are several ways to find this. ... What is the square root of 25? What is the ...
So #sqrt(16/25) = sqrt((4/5)^2) = 4/5# #-4/5# is also a square root of #16/25# , but by convention when we say the square root, we tend to mean the positive one. Answer link
1.5 15^2 = 225, so 2.25 = 225/100 = 225/(10^2) and sqrt(2.25) = sqrt((15^2)/(10^2)) = 15/10 = 1.5. Some situations one way works well and at another time it is not so good.

sqrt(25) = 5 A square root of a number n is a number r such that r^2 = n In the case of 25 we find that 5^2 = 25, so 5 is a square root of 25. Note that -5 is also a square root of 25, in that: (-5)^2 = (-5)xx(-5) = 25 "The" square root usually refers to the positive square root, sometimes known as the principal square root. In symbols, we ...

An integer is also called a whole number . It is not usual for square roots to be integers. This only happens if the number under de root is a square. This is because square-rooting is just the opposite operation from squaring. sqrtx means: give me the number of which x is the square. Example with non-integer: sqrt2=1.414213562... (this goes on, but NO calculator can give all the decimals ...
