Show Solution

Find the roots

d_{1} = - \frac{6 2 \times 13 1 ^{5}}{131}, d_{2} = \frac{6 2 \times 13 1 ^{5}}{131}

Alternative Form

d_{1} \approx - 0.498073, d_{2} \approx 0.498073

Evaluate

d \times d^{5} \times 655 - 10

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

d \times d^{5} \times 655 - 10 = 0

Multiply the terms

d \times d^{5} \times 655

Multiply the terms with the same base by adding their exponents

d^{1 + 5} \times 655

Add the numbers

d^{6} \times 655

Use the commutative property to reorder the terms

655 d^{6}

655 d^{6} - 10 = 0

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

655 d^{6} = 0 + 10

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

655 d^{6} = 10

Divide both sides

\frac{655 d ^{6}}{655} = \frac{10}{655}

Divide the numbers

d^{6} = \frac{10}{655}

Cancel out the common factor 5

d^{6} = \frac{2}{131}

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

d = \pm 6 \frac{2}{131}

Evaluate

6 \frac{2}{131}

To take a root of a fraction,take the root of the numerator and denominator separately

\frac{6 2}{6 131}

Multiply by the Conjugate

\frac{6 2 \times 6 13 1 ^{5}}{6 131 \times 6 13 1 ^{5}}

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

\frac{6 2 \times 13 1 ^{5}}{6 131 \times 6 13 1 ^{5}}

Multiply the numbers

More Steps

Evaluate

6131 \times 6 13 1^{5}

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

6 131 \times 13 1^{5}

Calculate the product

6 13 1^{6}

Reduce the index of the radical and exponent with 6

131

\frac{6 2 \times 13 1 ^{5}}{131}

d = \pm \frac{6 2 \times 13 1 ^{5}}{131}

Separate the equation into 2 possible cases

d = \frac{6 2 \times 13 1 ^{5}}{131} d = - \frac{6 2 \times 13 1 ^{5}}{131}

Solution

d_{1} = - \frac{6 2 \times 13 1 ^{5}}{131}, d_{2} = \frac{6 2 \times 13 1 ^{5}}{131}

Alternative Form

d_{1} \approx - 0.498073, d_{2} \approx 0.498073
