musickatia [10]

<h2>Answer</h2>

The answer to this question is 0.9

<h2>Explanation</h2>

We know that

sequre of 9 is equal to 81 as $9^2 = 81$

Then sequre of 0.9 will be

$0.9^2 = 0.81$

So,

b = $\sqrt{ 0.81}$

b = $\sqrt{ 0.9^2}$

Exponent and square root cancel out each other

So, the answer is 0.9.
