Solve 88870/80-1c^481

Question

Simplify the expression

\frac{8887}{8} - 81 c^{4}

Show Solution

\frac{1}{8} (8887 - 648 c^{4})

Show Solution

c_{1} = - \frac{4 17774}{6}, c_{2} = \frac{4 17774}{6}

Alternative Form

c_{1} \approx - 1.924399, c_{2} \approx 1.924399

Evaluate

\frac{88870}{80} - 1 \times c^{4} \times 81

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

\frac{88870}{80} - 1 \times c^{4} \times 81 = 0

Cancel out the common factor 10

\frac{8887}{8} - 1 \times c^{4} \times 81 = 0

Multiply the terms

More Steps

\frac{8887}{8} - 81 c^{4} = 0

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

- 81 c^{4} = 0 - \frac{8887}{8}

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

- 81 c^{4} = - \frac{8887}{8}

Change the signs on both sides of the equation

81 c^{4} = \frac{8887}{8}

Multiply by the reciprocal

81 c^{4} \times \frac{1}{81} = \frac{8887}{8} \times \frac{1}{81}

Multiply

c^{4} = \frac{8887}{8} \times \frac{1}{81}

Multiply

More Steps

c^{4} = \frac{8887}{648}

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

c = \pm 4 \frac{8887}{648}

Simplify the expression

More Steps

c = \pm \frac{4 17774}{6}

Separate the equation into 2 possible cases

c = \frac{4 17774}{6} c = - \frac{4 17774}{6}

Solution

c_{1} = - \frac{4 17774}{6}, c_{2} = \frac{4 17774}{6}

Alternative Form

c_{1} \approx - 1.924399, c_{2} \approx 1.924399
