Question

Вычислите 7,8*(0,1)^3/0,13*(0,2)^2

Answer 1

$0,1^3=0,001= \frac{1}{1000}$
$0,2^2 = 0,04 = \frac{4}{100}$
$7,8 = \frac{78}{10}$
$0,13 = \frac{13}{100}$
$\frac{78}{10} * \frac{1}{1000} : \frac{13}{100} * \frac{4}{100} = \frac{78}{10000} * \frac{10000}{52} = \frac{78}{52} = 1,5$

Answer 2

(7,8*0,001)/(0,13*0,04)=0,00078/0,0052=1,5
