Solve h^3388-4 - ScanMath

Question

Simplify the expression

388 h^{3} - 4

Evaluate

h^{3} \times 388 - 4

Solution

388 h^{3} - 4

Show Solution

4 (97 h^{3} - 1)

Evaluate

h^{3} \times 388 - 4

Use the commutative property to reorder the terms

388 h^{3} - 4

Solution

4 (97 h^{3} - 1)

Show Solution

h = \frac{3 9409}{97}

Alternative Form

h \approx 0.217642

Evaluate

h^{3} \times 388 - 4

To find the roots of the expression,set the expression equal to 0

h^{3} \times 388 - 4 = 0

Use the commutative property to reorder the terms

388 h^{3} - 4 = 0

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

388 h^{3} = 0 + 4

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

388 h^{3} = 4

Divide both sides

\frac{388 h ^{3}}{388} = \frac{4}{388}

Divide the numbers

h^{3} = \frac{4}{388}

Cancel out the common factor 4

h^{3} = \frac{1}{97}

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

3 h^{3} = 3 \frac{1}{97}

Calculate

h = 3 \frac{1}{97}
