Solution

More Steps

Evaluate

d \times d^{6} \times 629

Multiply the terms with the same base by adding their exponents

d^{1 + 6} \times 629

Add the numbers

d^{7} \times 629

Use the commutative property to reorder the terms

629 d^{7}

629 d^{7} - 100

Show Solution

d = \frac{7 100 \times 62 9 ^{6}}{629}

Alternative Form

d \approx 0.768966

Evaluate

d \times d^{6} \times 629 - 100

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

d \times d^{6} \times 629 - 100 = 0

More Steps

Multiply the terms

d \times d^{6} \times 629

Multiply the terms with the same base by adding their exponents

d^{1 + 6} \times 629

Add the numbers

d^{7} \times 629

Use the commutative property to reorder the terms

629 d^{7}

629 d^{7} - 100 = 0

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

629 d^{7} = 0 + 100

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

629 d^{7} = 100

Divide both sides

\frac{629 d ^{7}}{629} = \frac{100}{629}

Divide the numbers

d^{7} = \frac{100}{629}

Take the 7 -th root on both sides of the equation

7 d^{7} = 7 \frac{100}{629}

Calculate

d = 7 \frac{100}{629}

Solution

More Steps

Evaluate

7 \frac{100}{629}

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

\frac{7 100}{7 629}

Multiply by the Conjugate

\frac{7 100 \times 7 62 9 ^{6}}{7 629 \times 7 62 9 ^{6}}

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

\frac{7 100 \times 62 9 ^{6}}{7 629 \times 7 62 9 ^{6}}
