expand (2m+0.2)^3

expand

(2 m + 0.2)^{3}

8 m^{3} + 2.4 m^{2} + 0.24 m + 0.008

Solution steps

(2 m + 0.2)^{3}

Apply Perfect Cube Formula:

(a + b)^{3} = a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3}

(2 m + 0.2)^{3} = (2 m)^{3} + 3 (2 m)^{2} \cdot 0.2 + 3 \cdot 2 m \cdot 0. 2^{2} + 0. 2^{3}

= (2 m)^{3} + 3 (2 m)^{2} \cdot 0.2 + 3 \cdot 2 m \cdot 0. 2^{2} + 0. 2^{3}

Simplify

(2 m)^{3} + 3 (2 m)^{2} \cdot 0.2 + 3 \cdot 2 m \cdot 0. 2^{2} + 0. 2^{3} : 8 m^{3} + 2.4 m^{2} + 0.24 m + 0.008

= 8 m^{3} + 2.4 m^{2} + 0.24 m + 0.008

(p^{2} + 3)^{0}

\frac{2}{4} x - \frac{2}{8} x + \frac{4}{x ^{2}}

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

2 (x - 1) + 1

(2 x - 1) (2 x + 1) (4 x^{2} + 1) (16 x^{4} + 1) + 1 - 256 x^{8}
