Answer:We have to expand (5x+3y) whole cube ,
Do firstly use the identity of (a+b)3 that is a3 +b3 + 3a2b + 3ab2
Step-by-step explanation:Now we can apply this identity to our question !!
=(5x)3 + (3y)3 + 3(5x)(5x)(3y) + 3(5x)(3y)(3y)
=125x3 + 27y3 + 225x2y + 135xy2
Hence our Answer is 125x3 + 27y3 + 225x2y + 135xy2
