Question

$\sqrt{1.21} + \sqrt{0.64} - \sqrt{2.89}$
=?​

Answer 1

$\sf \sqrt{1.21}+ \sqrt{0.64} -\sqrt{2.89}$

$\bullet\sf 1.1\times 1.1= 1.21$

$\bullet\sf 0.8\times 0.8= 0.64$

$\bullet\sf 1.7\times 1.7= 2.89$

$\sf\implies \sqrt{1.1\times 1.1}+ \sqrt{0.8\times 0</p><p>8} -\sqrt{1.7\times 1.7 }$

$\sf\implies 1.1+0.8 -1.7$

$\sf\implies 1.9-1.7$

$\longrightarrow\sf 0.2$

Answer 2

Answer:

☺️ hello mate ☺️

Question :➡️

$find \: the \: value \: of ⟹\: \\ \: \sqrt{1.21} + \sqrt{0.64} - \sqrt{2.89}$

Solution :➡️

basic information :

$\sqrt{1.21} = 1.1 \\ \sqrt{0.64} = 0.8 \\ \sqrt{2.89} = 1.7$

therefore

$1.1 + 0.8 - 1.7 \\⇒1.9 - 1.7 \\ ⇒0.2$

hope it helps ✌️✌️
