Solve 20-2l^6 - ScanMath

Evaluate

20 - 2 l^{6}

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

20 - 2 l^{6} = 0

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

- 2 l^{6} = 0 - 20

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

- 2 l^{6} = - 20

Change the signs on both sides of the equation

2 l^{6} = 20

Divide both sides

\frac{2 l ^{6}}{2} = \frac{20}{2}

Divide the numbers

l^{6} = \frac{20}{2}

Divide the numbers

More Steps

l^{6} = 10

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

l = \pm 610

Separate the equation into 2 possible cases

l = 610 l = - 610

Solution

l_{1} = - 610, l_{2} = 610

Alternative Form

l_{1} \approx - 1.467799, l_{2} \approx 1.467799
