1. Decomponha o radicando em fatores primos calcule o valor de cada radical. a) sqrt [5](32) c) sqrt [3]((729)/(64)) e) sqrt [4]((625)/(256)) b) sqrt [3](343) d) sqrt (121) f) sqrt [5]((1)/(1024))

a) $$\sqrt [5]{32} = \sqrt [5]{2^5} = 2$$

b) $$\sqrt [3]{343} = \sqrt [3]{7^3} = 7$$

c) $$\sqrt [3]{\frac {729}{64}} = \sqrt [3]{\frac {9^3}{4^3}} = \frac {9}{4}$$

d) $$\sqrt {121} = \sqrt {11^2} = 11$$

e) $$\sqrt [4]{\frac {625}{256}} = \sqrt [4]{\frac {5^4}{4^4}} = \frac {5}{4}$$

f) $$\sqrt [5]{\frac {1}{1024}} = \sqrt [5]{\frac {1}{2^{10}}} = \frac {1}{2^2} = \frac {1}{4}$$
