Question

Срочно помогите (номера 2,3,4,5)

Answer 1

1)
$sqrt[4]{(-11)^4}=11$


2)
$sqrt[4]{160000*0.0625}=sqrt[4]{20^4*0.5^4}=20*0.5=10$


3)
$frac{sqrt[4]{128}}{sqrt[4]{8}}=sqrt[4]{frac{128}{8}}=sqrt[4]{16}=2$


4)
$sqrt[3]{4}*sqrt[3]{16}=sqrt[3]{4*16}=sqrt[3]{4^3}=4$


5)
$frac{2sqrt{75}-4sqrt{8}+8sqrt{2}}{3sqrt{27}+4sqrt{75}}=frac{2sqrt{5^2*3}-4sqrt{2*2^2}+8sqrt{2}}{3sqrt{3^2*3}+4sqrt{5^2*3}}=frac{10sqrt{3}-8sqrt{2}+8sqrt{2}}{9sqrt{3}+20sqrt{3}}=frac{10sqrt{3}}{29sqrt{3}}=frac{10}{29}$


6)
$sqrt[3]{80a^3}=asqrt{80}\sqrt[6]{5x^6}=|x|*sqrt[6]{5}=-xsqrt[6]{5}$
