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) = 5i -25 has two square roots 5i and -5i, but the expression sqrt(-25) denotes the principal square root, which by convention is 5i.
Help. sqrt (6.25) = 2.5 There are several ways to find this. For example: sqrt (6.25) = sqrt (6+1/4) = sqrt (25/4) = sqrt (25)/sqrt (4) = 5/2 = 2.5 sqrt (6.25) = sqrt (625/100) = sqrt (625)/sqrt (100) = 25/10 = 2.5.
sqrt(156.25) = 25/2 15625 = 5^6 So 156.25 = (5^6)/100 = (5^6)/(2^2*5^2) = 5^4/2^2 If a, b >= 0, then sqrt(a/b) = sqrt(a)/sqrt(b) If a, b, c > 0 then a^(bc) = (a^b)^c ...

A square root of a number n is a number r such that r2 = n. In the case of 25 we find that 52 = 25, so 5 is a square root of 25. Note that −5 is also a square root of 25, in that: (− 5)2 = (− 5) × (− 5) = 25."The" square root usually refers to the positive square root, sometimes known as the principal square root. In symbols, we write ...
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
