Question

Помогите пожалуйста!!!​

Answer 1

$2)$

$sqrt{0.49}-sqrt[3]{-15frac{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]{-4frac{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$
