Question

qual o valor da tais quadrada de 12​

Answer 1

• Acho que o nome acima é raiz quadrada

$\sf \sqrt{12}\\\\\\=\sqrt{2^2\cdot \:3}\\\\\\{Aplique\:as\:propriedades\:dos\:radicais}:\to\quad \sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0\\\\\\\sqrt{2^2\cdot \:3}=\sqrt{2^2}\sqrt{3}\\\\\\=\sqrt{2^2}\sqrt{3}\\\\\\{Aplique\:as\:propriedades\:dos\:radicais}:\iff\quad \sqrt{a^2}=a,\:\quad \:a\ge 0\\\\\\\sqrt{2^2}=2\\\\\\\to\boxed{\sf =2\sqrt{3}}$

Answer 2

Olá,

$\sqrt{12}$

$= \sqrt{4 \times 3}$

$= \sqrt{4} \times \sqrt{3}$

$= 2 \sqrt{3}$
