Gente,preciso mais uma vez da ajuda de vcs •_•​

Answer 1

Cálculos:

$\Large\purple{ \sf \sqrt{25\cdot4}=\sqrt{100}=10}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

Nesse problema,fazemos o inverso do sinal,para acharmos qual é o valor que multiplica pra dar 144,ou seja,divisão:

$\Large{ \sf 144\div16=9}$

Agora que achamos o valor,seguimos os cálculos:

$\Large\red{ \rm \sqrt{9\div16}=\sqrt{144}=12}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

$\Large\green{\text{ \rm \sqrt{\dfrac{100}{25}}=\sqrt{4}=2 }}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

$\Large\pink{\text{ \sf \sqrt{\dfrac{1}{4}}=\dfrac{1}{2} }}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

$\Large\orange{ \sf \sqrt{16+9}=\sqrt{25}=5}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

$\Large{ \sf \sqrt{100-36}=\sqrt{64}=8}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

$\Large{ \sf \sqrt{25+0}=\sqrt{25}=5}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

Logo o valor será 0,pois a raiz quadrada de 0 sempre será 0
