Solve (12i-5)^3 - ScanMath

Evaluate

(12 i - 5)^{3}

Use (a - b)^{3} = a^{3} - 3 a^{2} b + 3 a b^{2} - b^{3} to expand the expression

(12 i)^{3} - 3 (12 i)^{2} \times 5 + 3 \times 12 i \times 5^{2} - 5^{3}

Evaluate

More Steps

- 1728 i - 3 (12 i)^{2} \times 5 + 3 \times 12 i \times 5^{2} - 5^{3}

Evaluate

More Steps

- 1728 i + 2160 + 3 \times 12 i \times 5^{2} - 5^{3}

Evaluate

More Steps

- 1728 i + 2160 + 900 i - 5^{3}

Evaluate

- 1728 i + 2160 + 900 i - 125

Simplify the expression

- 828 i + 2035

Solution

2035 - 828 i
