Answer 1

Hello Buddy,

Thanks For Asking the Question,

Your Answer is Below

----------------------------------------------------------------------------------------------

Q1. $(\frac{1}{2} )^{2} \ + \sqrt{0.25}$

Sol:- 0.25 = $0.5^{2}$

⇒  $\frac{1^{2} }{\\ 2^{2} } + \sqrt{0.5^{2}$

⇒ $\frac{1}{4} + 0.5$

∵ $\frac{1}{4}= 0.25$

⇒ 0.25 + 0.5

⇒ 0.75

                       $\huge{\ornage{\boxed{\boxed{\pink{\green{\mathscr{ (\frac{1}{2} )^{2 } }+\sqrt{0.25}}=0.75} }} }}}$

Q2.   $( - \sqrt{\frac{4}{5} }) \ (-\sqrt{\frac{81}{100} } )$

⇒ $-(\frac{\sqrt{4}}\sqrt{5}}) \ (-\frac{\sqrt{81} }{\sqrt{100} } )$

∵  $\sqrt{4} =2\ , \sqrt{81} =9\ and\ \sqrt{100} = 10$

simplifying the expression, we get

⇒ $(\frac{2}{\sqrt{5} } ) \ (\frac{9}{10})$

Note:-  ( - ) × ( - ) =  ( + ) so answer will be positive

rationalizing $\frac{2}{\sqrt{5} }$ - Multiply and divide by  $\frac{\sqrt{5} }{\sqrt{5} }$  

⇒ $\frac{2}{\sqrt{5} }$  ×  $\frac{\sqrt{5} }{\sqrt{5} }$  × $(\frac{9}{10} )$

⇒ $\frac{2\sqrt{5} }{5} \ ( \frac{9}{10} )$

⇒ $\frac{2\ * \ 9\sqrt{5\ } }{5 \ * \ 10}$

⇒ $\frac{9\sqrt{5} }{5 \ * \ 5 }$

⇒ $\frac{9\sqrt{5} }{25}$

                 $\huge{\ornage{\boxed{\boxed{\pink{\green{\mathscr{ (-\frac{\sqrt{4} }{\sqrt{5} } ) }\ (-\frac{\sqrt{81} }{\sqrt{100} }) = \frac{9\sqrt{5} }{25} }} }}}$
