Solve h^3288-27 - ScanMath

Question

Simplify the expression

288 h^{3} - 27

Evaluate

h^{3} \times 288 - 27

Solution

288 h^{3} - 27

Show Solution

9 (32 h^{3} - 3)

Evaluate

h^{3} \times 288 - 27

Use the commutative property to reorder the terms

288 h^{3} - 27

Solution

9 (32 h^{3} - 3)

Show Solution

h = \frac{3 6}{4}

Alternative Form

h \approx 0.45428

Evaluate

h^{3} \times 288 - 27

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

h^{3} \times 288 - 27 = 0

Use the commutative property to reorder the terms

288 h^{3} - 27 = 0

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

288 h^{3} = 0 + 27

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

288 h^{3} = 27

Divide both sides

\frac{288 h ^{3}}{288} = \frac{27}{288}

Divide the numbers

h^{3} = \frac{27}{288}

Cancel out the common factor 9

h^{3} = \frac{3}{32}

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

3 h^{3} = 3 \frac{3}{32}

Calculate

h = 3 \frac{3}{32}
