Solve 4b^2 8b 7=4

Evaluate

4 b^{2} \times 8 b \times 7 = 4

Multiply

More Steps

224 b^{3} = 4

Divide both sides

\frac{224 b ^{3}}{224} = \frac{4}{224}

Divide the numbers

b^{3} = \frac{4}{224}

Cancel out the common factor 4

b^{3} = \frac{1}{56}

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

3 b^{3} = 3 \frac{1}{56}

Calculate

b = 3 \frac{1}{56}

Solution
