Solve l^435-1 - ScanMath

Question

Simplify the expression

35 l^{4} - 1

Evaluate

l^{4} \times 35 - 1

Solution

35 l^{4} - 1

Show Solution

l_{1} = - \frac{4 42875}{35}, l_{2} = \frac{4 42875}{35}

Alternative Form

l_{1} \approx - 0.411134, l_{2} \approx 0.411134

Evaluate

l^{4} \times 35 - 1

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

l^{4} \times 35 - 1 = 0

Use the commutative property to reorder the terms

35 l^{4} - 1 = 0

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

35 l^{4} = 0 + 1

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

35 l^{4} = 1

Divide both sides

\frac{35 l ^{4}}{35} = \frac{1}{35}

Divide the numbers

l^{4} = \frac{1}{35}

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

l = \pm 4 \frac{1}{35}

l = \pm \frac{4 42875}{35}

Separate the equation into 2 possible cases

l = \frac{4 42875}{35} l = - \frac{4 42875}{35}

Solution

l_{1} = - \frac{4 42875}{35}, l_{2} = \frac{4 42875}{35}

Alternative Form

l_{1} \approx - 0.411134, l_{2} \approx 0.411134
