Solve l^66-1 - ScanMath

Question

Simplify the expression

6 l^{6} - 1

Evaluate

l^{6} \times 6 - 1

Solution

6 l^{6} - 1

Show Solution

l_{1} = - \frac{6 7776}{6}, l_{2} = \frac{6 7776}{6}

Alternative Form

l_{1} \approx - 0.741836, l_{2} \approx 0.741836

Evaluate

l^{6} \times 6 - 1

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

l^{6} \times 6 - 1 = 0

Use the commutative property to reorder the terms

6 l^{6} - 1 = 0

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

6 l^{6} = 0 + 1

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

6 l^{6} = 1

Divide both sides

\frac{6 l ^{6}}{6} = \frac{1}{6}

Divide the numbers

l^{6} = \frac{1}{6}

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

l = \pm 6 \frac{1}{6}

Evaluate

66 \times 6 6^{5}

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

6 6 \times 6^{5}

Calculate the product

6 6^{6}

Reduce the index of the radical and exponent with 6

6

\frac{6 7776}{6}

l = \pm \frac{6 7776}{6}

Separate the equation into 2 possible cases

l = \frac{6 7776}{6} l = - \frac{6 7776}{6}

Solution

l_{1} = - \frac{6 7776}{6}, l_{2} = \frac{6 7776}{6}

Alternative Form

l_{1} \approx - 0.741836, l_{2} \approx 0.741836
