Question

transforma P a radical simple
P= √18 -2√32

Answer 1

Explicación paso a paso:

$P = \sqrt{18} - 2 \sqrt{32}$

$\: \: \: \: \: = \sqrt{9 \times 2} - 2 \sqrt{16 \times 2}$

$\: \: \: \: \: = ( \sqrt{9} \times \sqrt{2} ) - 2( \sqrt{16 } \times \sqrt{2} )$

$\: \: \: \: \: = (3 \times \sqrt{2}) - 2(4 \times \sqrt{2} )$

$\: \: \: \: \: = 3 \sqrt{2} - 2(4 \sqrt{2} )$

$\: \: \: \: \: = 3 \sqrt{2} - 8 \sqrt{2}$

$\: \: \: \: \: = (3 - 8) \sqrt{2}$

$\: \: \: \: \: = - 5 \sqrt{2}$
