Answer 1

$\large\fbox\red{A}\small\fbox\orange{N}\large\fbox\pink{S}\small\fbox\green{W}\large\fbox\blue{E}\small\fbox\purple{R}$

$64x^{3} - 125y^{3}$

$4^{3}x^{3} - 5^{3}y^{3}$

$(4x)^{3} - (5y)^{3}$

$(4x - 5y) \times ((4x)^{2} + 4x \times 5y + (5y)^{2} )$

$(4x - 5y) \: \times (16x^{2} + 20xy + 25y^{2} )$
