Question

Calcule, faturando e radicando. ( não consegui digitar tudo)

Answer 1

$a) \sqrt{256}= \sqrt{2^4.2^4}=\sqrt{16.16}=16\\\\b)\sqrt{729}=\sqrt{3^6}=\sqrt{3^4.3^2}=\sqrt{81.9}=9.3=27\\\\c) \sqrt[3]{343} = \sqrt[3]{7^3} =7\\\\d)\sqrt[5]{1024} =\sqrt[5]{2^{10}} =\sqrt[5]{2^5.2^5}=4\\\\e) \sqrt{1296} =\sqrt{2^4.3^4}=\sqrt{16.81}=4.9=36\\\\f)\sqrt{1089} =\sqrt{11^2.3^2}=11.3=33$

Answer 2

Resposta:

$\sqrt{256}= 16\\\\\sqrt{729}=27\\\\\sqrt[3]{343}=7\\\\\sqrt[5]{1024}=4\\\\\sqrt{1296}=36\\\\\sqrt{1089}= 33$
