Question

Raiz quadrada aproximada de 102

Answer 1

Raiz quadrada aproximada de 102

$\sqrt{N}\approx\dfrac{N + B}{2\sqrt{B}} \\\\\\ \sqrt{102}\approx\dfrac{102 + 100}{2\sqrt{100}} \\\\\\ \sqrt{102}\approx\dfrac{202}{2\cdot10} \\\\\\ \sqrt{102}\approx\dfrac{202}{20} \\\\\\ \sqrt{102}\approx\ 10,1$


Essa fórmula costuma trazer valores arredondados , no caso ela trouxe arredondado para 10,1.


Resposta :

√102 ≈ 10,1

Answer 2

$\mathsf{F\acute ormula:~\sqrt n\approxeq\dfrac{n+Q}{2\sqrt Q}}$

$\mathsf{ \sqrt{102}\approxeq\dfrac{ 102+100}{2\sqrt{100}}=\dfrac{202}{2\cdot10}}$

$\boxed{\boxed{\mathsf{\sqrt{102}\approxeq\dfrac{202}{20}= 10{,}1 }}}$
