Answer 1

Explicação passo a passo:

$a)~~\sqrt{+64} =+8\\ \\ b)~~\sqrt{-10} \to n\tilde{a}o~~existe~~em~~R\\ \\ c)~~\sqrt{-16} \to n\tilde{a}o~~existe~~em~~R\\ \\ d)~~\sqrt{+9} =+3\\ \\ e)~~\sqrt[3]{-8} =\sqrt[3]{-2^3} =-2\\ \\ f)~~\sqrt[3]{+64} =\sqrt[3]{+4^3} =+4\\ \\ g)~~\sqrt{25} =5\\ \\ h)~~\sqrt[3]{-125} =\sqrt[3]{-5^3} =-5\\ \\ i)~~\sqrt[3]{8} =\sqrt[3]{2^3} =2$
