Solve f^28f - 25 = 0

Evaluate

f^{2} \times 8 f - 25 = 0

Multiply

More Steps

8 f^{3} - 25 = 0

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

8 f^{3} = 0 + 25

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

8 f^{3} = 25

Divide both sides

\frac{8 f ^{3}}{8} = \frac{25}{8}

Divide the numbers

f^{3} = \frac{25}{8}

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

3 f^{3} = 3 \frac{25}{8}

Calculate

f = 3 \frac{25}{8}

Solution

More Steps

f = \frac{3 25}{2}
