Answer 1

Ответ:

(8в+8)²/в × в/4в+в =(8в+8)²/4в+4= 16в+16 = -15+16 =1

Answer 2

$\dfrac{64b^2+128b+64}b:\bigg(\dfrac4b+4\bigg)=\dfrac{64(b^2+2b+1)}b:\dfrac{4+4b}b=\dfrac{}{}\dfrac{64(b+1)^2}b\cdot\dfrac{b}{4(b+1)}=$

$=\dfrac{16(b+1)}{1}=16b+16$

$\pi pu\ b=-\dfrac{15}{16}$

$16\bigg(-\dfrac{15}{16}\bigg)+16=-\dfrac{15}1+16=16-15=1$
