VAMOS A SUA PERGUNTA:》》

$\sf5 [ ( 21 + 7 \sqrt { 9 } ) \div 3 ^ { 1 } ( 27 - 5 \sqrt { 16 } ) ] \div \sqrt { 4 } 9 =$

$\sf9\times \left(\dfrac{5\times \left(\dfrac{21+7\times 3}{3^{1}}\right)\left(27-5\sqrt{16}\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{5\times \left(\dfrac{21+21}{3^{1}}\right)\left(27-5\sqrt{16}\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{5\times \left(\dfrac{42}{3^{1}}\right)\left(27-5\sqrt{16}\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{5\times \left(\dfrac{42}{3}\right)\left(27-5\sqrt{16}\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{5\times 14\left(27-5\sqrt{16}\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{70\left(27-5\sqrt{16}\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{70\left(27-5\times 4\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{70\left(27-20\right)}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{70\times 7}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{490}{\sqrt{4}}\right)=2205$

$\sf9\times \left(\dfrac{490}{2}\right)=2205$

$9\times 245=2205$

$\boxed{\bold{\displaystyle{\clubsuit\ \spadesuit\ \maltese \ \sf \red{ = 2205} }}}\ \checkmark$
