Question

decomponha o radicando em fatores primos e calcule a raiz de64​

Answer 1

Olá,

$\sqrt{64}$

64 | 2

32 | 2

16 | 2

8 | 2

4 | 2

2 | 2

1

Assim:

$64 = 2 \times 2 \times 2 \times 2\times 2 \times 2$

$64 = {2}^{2} \times {2}^{2} \times {2}^{2}$

$\sqrt{64} = \sqrt{ {2}^{2} \times {2}^{2} \times {2}^{2} }$

$\sqrt{64} = 2 \times 2 \times 2$

$\sqrt{64} = 8$
