Question

Помогите пожалуйста!!!​

Answer 1

$2)$

$\sqrt{0.49}-\sqrt[3]{-15\frac{5}{8}}+\sqrt[5]{32}=\sqrt{(0.7)^2}+\sqrt[3]{\frac{125}{8}}+\sqrt[5]{2^5}=$$=0.7+\sqrt[3]{(\frac{5}{2})^3}+2=0.7+2.5+2=5.2$

$4)$

$\sqrt{1.21}+\sqrt[3]{-4\frac{12}{125}}+\sqrt[4]{625}=\sqrt{(1.1)^2}-\sqrt[3]{\frac{512}{125}}+\sqrt[4]{5^4}=$$=1.1-\sqrt[3]{(\frac{8}{5})^3}+5=1.1-1.6+5=-0.5+5=4.5$
