Solve 2c^45=66 - ScanMath

Evaluate

2 c^{4} \times 5 = 66

Multiply the terms

10 c^{4} = 66

Divide both sides

\frac{10 c ^{4}}{10} = \frac{66}{10}

Divide the numbers

c^{4} = \frac{66}{10}

Cancel out the common factor 2

c^{4} = \frac{33}{5}

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

c = \pm 4 \frac{33}{5}

Simplify the expression

More Steps

c = \pm \frac{4 4125}{5}

Separate the equation into 2 possible cases

c = \frac{4 4125}{5} c = - \frac{4 4125}{5}

Solution

c_{1} = - \frac{4 4125}{5}, c_{2} = \frac{4 4125}{5}

Alternative Form

c_{1} \approx - 1.602825, c_{2} \approx 1.602825
