Question

SOS!Упростите выражение: 3√2*12√8

Answer 1

$3 sqrt2 * frac{1}{2} sqrt{8} =3 sqrt{2} * frac{1}{2} sqrt{4*2} = frac{3 sqrt{2}*2 sqrt{2} }{2} = frac{3*2*2}{2} =6$

Answer 2

$3 sqrt{2}* frac{1}{2} sqrt{8}= 3 sqrt{2}* frac{1}{2} sqrt{4*2}=3 sqrt{2}* frac{1}{2}*2 sqrt{2}= 3 sqrt{2}* sqrt{2}=3*2=6$
