To Find :Simplify

Solution:

(\sqrt{81}+ \sqrt{0.81} + \sqrt{0.0081}) \times \sqrt{10000}(

\sqrt{81}=9

81

=9

\sqrt{0.81}=0.9

0.81

=0.9

\sqrt{0.0081}=0.09

0.0081

=0.09

\sqrt{10000}=100

10000

=100

Substitute the values in 1

(9+ 0.9 +0.09) \times 100(9+0.9+0.09)×100

(9.99) \times 100(9.99)×100

999999

Hence (\sqrt{81}+ \sqrt{0.81} + \sqrt{0.0081}) \times \sqrt{10000}=999(
