The answer must be B

Bcoz sqrt of a fraction number is always greater than the fraction number.

A. √0.81
B. √0.9
C. (0.9)2
D. (0.9)(0.99)
E. 1 - √0.01
We are given that x > 0.9 and need to determine a value for x.

We may recall that when we take the square root of a decimal that is between 0 and 1, the result is larger than the original number inside the root. Thus, since √0.9 > 0.9, we know that √0.9 could be x.

Answer: B
