Solve e^5-2697 v^2

Question

Find the roots

v_{1} = - \frac{e ^{2} 2697 e}{2697}, v_{2} = \frac{e ^{2} 2697 e}{2697}

Alternative Form

v_{1} \approx - 0.234583, v_{2} \approx 0.234583

Evaluate

e^{5} - 2697 v^{2}

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

e^{5} - 2697 v^{2} = 0

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

- 2697 v^{2} = 0 - e^{5}

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

- 2697 v^{2} = - e^{5}

Change the signs on both sides of the equation

2697 v^{2} = e^{5}

Divide both sides

\frac{2697 v ^{2}}{2697} = \frac{e ^{5}}{2697}

Divide the numbers

v^{2} = \frac{e ^{5}}{2697}

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

v = \pm \frac{e ^{5}}{2697}

Evaluate

e^{5}

Rewrite the exponent as a sum where one of the addends is a multiple of the index

e^{4 + 1}

Use a^{m + n} = a^{m} \times a^{n} to expand the expression

e^{4} \times e

The root of a product is equal to the product of the roots of each factor

e^{4} \times e

Reduce the index of the radical and exponent with 2

e^{2} e

\frac{e ^{2} e}{2697}

Multiply by the Conjugate

\frac{e ^{2} e \times 2697}{2697 \times 2697}

Multiply the numbers

More Steps

Evaluate

e \times 2697

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

e \times 2697

Calculate the product

2697 e

\frac{e ^{2} 2697 e}{2697 \times 2697}

When a square root of an expression is multiplied by itself,the result is that expression

\frac{e ^{2} 2697 e}{2697}

v = \pm \frac{e ^{2} 2697 e}{2697}

Separate the equation into 2 possible cases

v = \frac{e ^{2} 2697 e}{2697} v = - \frac{e ^{2} 2697 e}{2697}

Solution

v_{1} = - \frac{e ^{2} 2697 e}{2697}, v_{2} = \frac{e ^{2} 2697 e}{2697}

Alternative Form

v_{1} \approx - 0.234583, v_{2} \approx 0.234583
