HOPES IT HELPS!!!!

Answer 2

Answer:

$(\sqrt{81} + \sqrt{0.081} + \sqrt{0.0081} ) \times \sqrt{10000 }$

$= (9 + \sqrt{0.081} + 0.09) \times 100$

$= (9.09 + \sqrt{ \frac{81}{1000} } ) \times 100$

$= (9.09 + \frac{9}{10} \sqrt{ \frac{1}{10} } ) \times 100$

$= ( \frac{90.9 + 9}{10} \sqrt{ \frac{1}{10} } ) \times 100$

$= (99.9 \sqrt{ \frac{1}{10} }) 10$

$999 \sqrt{ \frac{1}{10} }$
