Solve e^5-2690 c^2

Question

Find the roots

c_{1} = - \frac{e ^{2} 2690 e}{2690}, c_{2} = \frac{e ^{2} 2690 e}{2690}

Alternative Form

c_{1} \approx - 0.234888, c_{2} \approx 0.234888

Evaluate

e^{5} - 2690 c^{2}

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

e^{5} - 2690 c^{2} = 0

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

- 2690 c^{2} = 0 - e^{5}

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

- 2690 c^{2} = - e^{5}

Change the signs on both sides of the equation

2690 c^{2} = e^{5}

Divide both sides

\frac{2690 c ^{2}}{2690} = \frac{e ^{5}}{2690}

Divide the numbers

c^{2} = \frac{e ^{5}}{2690}

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

c = \pm \frac{e ^{5}}{2690}

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}{2690}

Multiply by the Conjugate

\frac{e ^{2} e \times 2690}{2690 \times 2690}

Multiply the numbers

More Steps

Evaluate

e \times 2690

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

e \times 2690

Calculate the product

2690 e

\frac{e ^{2} 2690 e}{2690 \times 2690}

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

\frac{e ^{2} 2690 e}{2690}

c = \pm \frac{e ^{2} 2690 e}{2690}

Separate the equation into 2 possible cases

c = \frac{e ^{2} 2690 e}{2690} c = - \frac{e ^{2} 2690 e}{2690}

Solution

c_{1} = - \frac{e ^{2} 2690 e}{2690}, c_{2} = \frac{e ^{2} 2690 e}{2690}

Alternative Form

c_{1} \approx - 0.234888, c_{2} \approx 0.234888
