The required order of the number from least to greatest square root is
1/√3 < √1 < √2 < √2.5
Which number is greatest in value:
In the above numbers 1, 1/3 and 2.5 do not have square roots.
So, we will write 1, 1/3 and 2.5 inside the square root as shown below.
√1 = 1
√(1/3) = 1/√3 = 0.577350269
√2.5 = 1.58113883
√2 = 1.414
Arranging these numbers according to their value, we get the order as-
0.577350269 < 1 < 1.414 < 1.581138831
Hence, the required order of the number from least to greatest square root is 1/√3 < √1 < √2 < √2.5.
