Question

(6xsquare+5y cube)(6x square+5y cube​

Answer 1

Answer:

$36x^{4} + 60x^{2} y^{3} + 25y^{6}$

Step-by-step explanation:

$(6x^{2} +5y^{3})(6x^{2} +5y^{3})$

=$(6x^{2} +5y^{3})^{2}$

= $(6x^{2}) ^{2} + 2.(6x^{2}).5y^{3} +(5y^{3})^{2}$ [∵ $(a + b)^{2} = a^{2} + 2.a.b + b^{2}$]

= $36x^{4} + 60x^{2} y^{3} + 25y^{6}$
