Answer 1

Respuesta:

1.

$(4m^{n} +y^{n})^{2}\\(4m^{n})^{2}+2(4m^{n})(y^{n})+(y^{n})^{2}\\16m^{2n} +8m^{n}y^{n}+y^{2n}$

2.

$(3a^{n} +2b^{n+1})^{2} \\(3a^{n})^{2} +2(3a^{n})(2b^{n+1})+(2b^{n+1})^{2} \\9a^{2n} +12a^{n} b^{n+1} +4b^{2n+2}$

3.

$(5y^{m+1} -2x^{m})^{2} \\(5y^{m+1})^{2} - 2(5y^{m+1})(2x^{m})+(2x^{m})^{2}\\25y^{2m+2} -20y^{m+1} x^{m} +4x^{2m}$
