simplify (2x)^3+(3y)^3+(4z)^3-3(2x)(3y)(4z)

simplify

(2 x)^{3} + (3 y)^{3} + (4 z)^{3} - 3 (2 x) (3 y) (4 z)

8 x^{3} + 27 y^{3} + 64 z^{3} - 72 x yz

Solution steps

(2 x)^{3} + (3 y)^{3} + (4 z)^{3} - 3 (2 x) (3 y) (4 z)

(2 x)^{3} = 8 x^{3}

(3 y)^{3} = 27 y^{3}

(4 z)^{3} = 64 z^{3}

3 \cdot 2 x \cdot 3 y \cdot 4 z = 72 x yz

= 8 x^{3} + 27 y^{3} + 64 z^{3} - 72 x yz

6 x^{3} + 13 x^{2} + x - 2

x^{18} - y^{18}

(2^{x + 1} + 3)^{2}

sin^{3} (x) + sin^{2} (x) - sin (x)

(3 a - 7 b - c)^{2}
