Answer 1

A)

$( \frac{2}{3} bs^3)^3+3( \frac{2}{3} bs^3)^2.( \frac{5}{4}a^2)+3( \frac{2}{3} bs^3)( \frac{5}{4}a^2)^2+( \frac{5}{4} a^2)^3$

$\frac{8}{27} b^3s^9+3( \frac{4}{9}b^2s^6)( \frac{5}{4}a^2 ) +3( \frac{2}{3} bs^3)( \frac{25}{16} a^4)+ \frac{125}{64}a^6=$

$\frac{8}{27} b^3s^9+ \frac{5}{3} a^2b^2s^6+ \frac{25}{8} a^4bs^3+ \frac{125}{64} a^6$

B)

$(7xy)^2-(6m^3n^2)^2=49x^2y^2-36m^6n^4$

C)

$(x^3)^2+(2.x^3. \frac{2}{3} y)+( \frac{2}{3}y)^2=$

$x^6+ \frac{4}{3} x^3y+ \frac{4}{9} y^2$

D)

$(7y^2)^2+(2.7y^2.3y^4)+(3y^4)^2=$

$49y^4+42y^6+9y^8$
