Solve h^4868-4 - ScanMath

Question

Simplify the expression

868 h^{4} - 4

Evaluate

h^{4} \times 868 - 4

Solution

868 h^{4} - 4

Show Solution

4 (217 h^{4} - 1)

Evaluate

h^{4} \times 868 - 4

Use the commutative property to reorder the terms

868 h^{4} - 4

Solution

4 (217 h^{4} - 1)

Show Solution

h_{1} = - \frac{4 21 7 ^{3}}{217}, h_{2} = \frac{4 21 7 ^{3}}{217}

Alternative Form

h_{1} \approx - 0.260546, h_{2} \approx 0.260546

Evaluate

h^{4} \times 868 - 4

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

h^{4} \times 868 - 4 = 0

Use the commutative property to reorder the terms

868 h^{4} - 4 = 0

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

868 h^{4} = 0 + 4

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

868 h^{4} = 4

Divide both sides

\frac{868 h ^{4}}{868} = \frac{4}{868}

Divide the numbers

h^{4} = \frac{4}{868}

Cancel out the common factor 4

h^{4} = \frac{1}{217}

Take the root of both sides of the equation and remember to use both positive and negative roots

h = \pm 4 \frac{1}{217}

The product of roots with the same index is equal to the root of the product

4 217 \times 21 7^{3}

Calculate the product

4 21 7^{4}

Reduce the index of the radical and exponent with 4

217

\frac{4 21 7 ^{3}}{217}

h = \pm \frac{4 21 7 ^{3}}{217}

Separate the equation into 2 possible cases

h = \frac{4 21 7 ^{3}}{217} h = - \frac{4 21 7 ^{3}}{217}

Solution

h_{1} = - \frac{4 21 7 ^{3}}{217}, h_{2} = \frac{4 21 7 ^{3}}{217}

Alternative Form

h_{1} \approx - 0.260546, h_{2} \approx 0.260546
