Which applies the power of a product rule to simplify (5t)^3

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y

Marking brainliest for original answer.. are these two triangles similar? how can you tell?
