Question

Найдите значение произведения: 

1) $sqrt{500} * sqrt{3,2}$ 

 

2)$sqrt{500} * sqrt{1,25}$ 

 

3) $sqrt1{frac{1}{8}} * sqrt{0,72}$ 

Answer 1

1)  (√500)*(√3,2) = √1600 = 40

 

2) (√500)*(√1,25) = √625 = 25

 

3) (√1⅛)*(√0,72) = (√1,125)*(√0,72) = √0,81 = 0,9

Answer 2

$sqrt{500}*sqrt{3,2}=sqrt{500*3,2}=sqrt{1600}=40$

$sqrt{500}*sqrt{1,25}=sqrt{500*1,25}=sqrt{625}=25$

$sqrt{1frac{1}{8}}*sqrt{0,72}=sqrt{frac{9}{8}*0,72}}=sqrt{frac{9}{8}*{frac{72}{100}}}=sqrt{frac{9}{1}*{frac{9}{100}}}=frac{9}{10}$
