Question

Сполным и понятным ! 5*(2/5+x^2y^3)^2-(6+xy)^2

Answer 1

$5( \frac{2}{5} + x^{2} y^{3}) ^{2} -(6+xy) ^{2} =5( \frac{4}{25} + \frac{4}{5} x^{2} y^{3} + x^{4} y^{6}) - 36 - 12xy- x^{2} y^{2} =$$\frac{4}{5}+4 x^{2} y^{3}+5 x^{4}y ^{6}-36-12xy - x^{2} y^{2}=5 x^{4} y^{6}+4 x^{2} y^{3}- x^{2} y^{2}-12xy$$-35,2$

Answer 2

5*(2/5+x^2y^3)^2-(6+xy)^2=5(4/25+4/5x²y³+4/25x^4y^6)-36-12xy-x²y²=
=4/5+4x²y³+4/5x^4y^6-36-12xy-x²y²=-35 1/5+4x²y³+4/5x^4y^6-12xy-x²y²
