Solve \frac{3x^21}{4} \frac{x 9}{7}=11

Evaluate

\frac{3 x ^{2} \times 1}{4} \times \frac{x \times 9}{7} = 11

Simplify

More Steps

\frac{27 x ^{3}}{28} = 11

Cross multiply

27 x^{3} = 28 \times 11

Simplify the equation

27 x^{3} = 308

Divide both sides

\frac{27 x ^{3}}{27} = \frac{308}{27}

Divide the numbers

x^{3} = \frac{308}{27}

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

3 x^{3} = 3 \frac{308}{27}

Calculate

x = 3 \frac{308}{27}

Solution

More Steps

x = \frac{3 308}{3}
