Question

d)
$5\sqrt{1,44} + 3 \sqrt[3]{0,343}$

Answer 1

$5\sqrt{1.44}+3\sqrt[3]{0.343}=\\\\\\5\sqrt{\dfrac{144}{100}}+3\sqrt[3]{\dfrac{343}{1000}}=\\\\\\5\dfrac{\sqrt{144}}{\sqrt{100}}+3\dfrac{\sqrt[3]{343}}{\sqrt[3]{1000}}=\\\\\\5\cdot\dfrac{12}{10}+3\cdot\dfrac{7}{10}=\\\\\\\dfrac{60}{10}+\dfrac{21}{10}=\\\\\\\dfrac{81}{10}=\boxed{8.1}$
