Срочна .............
​

Answer 1

$\frac{4,5^{2}-1,5^{2}}{0,3*0,7-0,3}=\frac{(4,5-1,5)(4,5+1,5)}{0,3(0,7-1)}=\frac{3*6}{0,3*(-0,3)}=-\frac{18}{0,09}=\boxed{-200}$

Answer 2

Ответ:

Объяснение:

$\large \frac{4,5^{2}-1,5^{2}}{0,3*0,7-0.3}=\frac{(4,5-1,5)(4,5+1,5)}{0,3(0,7-1)}=\frac{3*6}{-0,09}=\mathbf{-200}$
