expressões.
c) V(2-5)
3/7
a) 335
d) 16)​

Answer 1

Oie, Td Bom?!

a)

$\sqrt[5]{3 {}^{5} } = \sqrt[5 \div 5]{3 {}^{5 \div 5} } = \sqrt[1]{3 {}^{1} } = 3$

b)

$\sqrt[3]{7 {}^{3} } = \sqrt[3 \div 3]{7 {}^{3 \div 3} } = \sqrt[1]{7 {}^{1} } = 7$

c)

$\sqrt[7]{(2 \: . \: 5) {}^{7} } = \sqrt[7 \div 7]{(2 \: . \: 5) {}^{7 \div 7} } = \sqrt[1]{(2 \: . \: 5) {}^{1} } = 2 \: . \: 5 = 10$

d)

$\sqrt{(5a {}^{2}) {}^{2} } = \sqrt[2 \div 2]{(5a {}^{2}) {}^{2 \div 2} } = \sqrt[1]{(5a {}^{2} ) {}^{1} } = 5a {}^{2}$
