Solve 512q^3-729=0

Evaluate

512 q^{3} - 729 = 0

Move the constant to the right-hand side and change its sign

512 q^{3} = 0 + 729

Removing 0 doesn't change the value,so remove it from the expression

512 q^{3} = 729

Divide both sides

\frac{512 q ^{3}}{512} = \frac{729}{512}

Divide the numbers

q^{3} = \frac{729}{512}

Take the 3 -th root on both sides of the equation

3 q^{3} = 3 \frac{729}{512}

Calculate

q = 3 \frac{729}{512}
