Answer 1

Respuesta:

1) Encierra en un círculo

$a. (-2\sqrt{2})y (-5\sqrt{2} )\\\\b.(0.1\sqrt{5} )y(-\pi \sqrt{5} )\\\\c.(\frac{2}{3}\sqrt{\pi } )y(\pi \sqrt{\pi } )\\\\d.(\frac{2}{3}\sqrt{\pi } )y(3\sqrt{\pi } )\\\\e.(-4\sqrt[3]{3} )y(5\sqrt[3]{3} )$

2.Simplifica

$a)\sqrt{20}\\\\\sqrt{5 * 4}\\\\\sqrt{5*2^2}\\\\\sqrt{5} *\sqrt{2^2}\\\\\sqrt{5}*2\\\\2\sqrt{5}$

$b)\sqrt{45}\\\\ \sqrt{9*5}\\\\\sqrt{3^2 * 5}\\\\\sqrt{3^2}* \sqrt{5}\\\\3\sqrt{5}$

$c)\sqrt[3]{128}\\\\\sqrt[3]{2^3 * 2^3 * 2}\\\\ \sqrt[3]{2^3}* \sqrt[2]{2^3}* \sqrt[3]{2}\\\\2 * 2 * \sqrt[3]{2}\\\\4\sqrt[3]{2}$

$d)\sqrt[3]{40}\\\\\sqrt[3]{2^3*5}\\\\\sqrt[3]{2^3}* \sqrt[3]{5}\\\\2 \sqrt[3]{5}$

$e)\sqrt{12}\\\\\sqrt{2^2 * 3}\\\\\sqrt{2^2}* \sqrt{3}\\\\2\sqrt{3}$

$f)\sqrt[4]{3^4} = 3$

$g)\sqrt[3]{5^{12}}\\\\\sqrt[3]{5^3 *5^3*5^3*5^3}\\\\\sqrt[3]{5^3}* \sqrt[3]{5^3}* \sqrt[3]{5^3}* \sqrt[3]{5^3}\\\\5 * 5 * 5 * 5\\\\625$

$h)\sqrt{3^4*2^6} \\\\\sqrt{3^2*3^2*2^2*2^2*2^2} \\\\\sqrt{3^2} *\sqrt{3^2}* \sqrt{2^2}* \sqrt{2^2}* \sqrt{2^2} \\\\3 * 3 *2 * 2 * 2\\\\9 * 8\\\\72$

$i)\sqrt{3^7}\\\\\sqrt{3^2*3^2*3^2*3}\\\\\sqrt{3^2}* \sqrt{3^2}* \sqrt{3^2} *\sqrt{3}\\\\3 * 3 * 3 * \sqrt{3}\\\\27\sqrt{3}$
