Apply the formula: $x+a=b$$\to x=b-a$, where $a=-4$, $b=0$, $x+a=b=2\sqrt[3]{7b-1}-4=0$, $x=2\sqrt[3]{7b-1}$ and $x+a=2\sqrt[3]{7b-1}-4$

$2\sqrt[3]{7b-1}=4$

Learn how to solve equations avec racines cubiques problems step by step online. Solve the equation with radicals 2(7b-1)^(1/3)-4=0. Apply the formula: x+a=b\to x=b-a, where a=-4, b=0, x+a=b=2\sqrt[3]{7b-1}-4=0, x=2\sqrt[3]{7b-1} and x+a=2\sqrt[3]{7b-1}-4. Apply the formula: cx^a=b\to \left(cx^a\right)^{inverse\left(a\right)}=b^{inverse\left(a\right)}, where a=\frac{1}{3}, x^ac=b=2\sqrt[3]{7b-1}=4, b=4, c=2, x=7b-1, x^a=\sqrt[3]{7b-1} and x^ac=2\sqrt[3]{7b-1}. Apply the formula: \left(ab\right)^n=a^nb^n, where a=2, b=\sqrt[3]{7b-1} and n=3. Apply the formula: ax=b\to \frac{ax}{a}=\frac{b}{a}, where a=8, b=64 and x=7b-1.

Final answer to the problem

$b=\frac{9}{7}$
