Solve l^45086-1 - ScanMath

Question

Simplify the expression

5086 l^{4} - 1

Evaluate

l^{4} \times 5086 - 1

Solution

5086 l^{4} - 1

Show Solution

l_{1} = - \frac{4 508 6 ^{3}}{5086}, l_{2} = \frac{4 508 6 ^{3}}{5086}

Alternative Form

l_{1} \approx - 0.118415, l_{2} \approx 0.118415

Evaluate

l^{4} \times 5086 - 1

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

l^{4} \times 5086 - 1 = 0

Use the commutative property to reorder the terms

5086 l^{4} - 1 = 0

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

5086 l^{4} = 0 + 1

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

5086 l^{4} = 1

Divide both sides

\frac{5086 l ^{4}}{5086} = \frac{1}{5086}

Divide the numbers

l^{4} = \frac{1}{5086}

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

l = \pm 4 \frac{1}{5086}
