Answer 1

xⁿ × yⁿ = (x × y)ⁿ

x³ - y³ = (x - y)(x² + xy + y²)

____________________

15³ - 2³ × 6³

=15³ - (2 × 6)³

=15³ - 12³

=(15 - 12)(15² + (15)(12) + 12²)

=3((15)(15) + 180 + (12)(12))

=3(225 + 180 + 144)

=3(225) + 3(180) + 3(144)

=675 + 540 + 432

=1.215 + 432

=1.647

Answer 2

15³ - 2³ × 6³

• 15³ (15 × 15 × 15)

• 2³ (2 × 2 × 2)

• 6³ (6 × 6 × 6)

• (15 × 15 × 15) - (2 × 2 × 2) × (6 × 6 × 6)

• 1.647
