Solve x⋅4x^27=90

Evaluate

x \times 4 x^{2} \times 7 = 90

Multiply

More Steps

28 x^{3} = 90

Divide both sides

\frac{28 x ^{3}}{28} = \frac{90}{28}

Divide the numbers

x^{3} = \frac{90}{28}

Cancel out the common factor 2

x^{3} = \frac{45}{14}

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

3 x^{3} = 3 \frac{45}{14}

Calculate

x = 3 \frac{45}{14}

Solution
