Question

Simplify the expression

651 d^{3} - 1

Evaluate

d \times d^{2} \times 651 - 1

Solution

More Steps

Evaluate

d \times d^{2} \times 651

Multiply the terms with the same base by adding their exponents

d^{1 + 2} \times 651

Add the numbers

d^{3} \times 651

Use the commutative property to reorder the terms

651 d^{3}

651 d^{3} - 1

Show Solution

d = \frac{3 65 1 ^{2}}{651}

Alternative Form

d \approx 0.115382

Evaluate

d \times d^{2} \times 651 - 1

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

d \times d^{2} \times 651 - 1 = 0

Multiply

More Steps

Multiply the terms

d \times d^{2} \times 651

Multiply the terms with the same base by adding their exponents

d^{1 + 2} \times 651

Add the numbers

d^{3} \times 651

Use the commutative property to reorder the terms

651 d^{3}

651 d^{3} - 1 = 0

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

651 d^{3} = 0 + 1

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

651 d^{3} = 1

Divide both sides

\frac{651 d ^{3}}{651} = \frac{1}{651}

Divide the numbers

d^{3} = \frac{1}{651}

Take the 3 -th root on both sides of the equation

3 d^{3} = 3 \frac{1}{651}

Calculate

d = 3 \frac{1}{651}

Solution

More Steps

Evaluate

3 \frac{1}{651}

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

\frac{3 1}{3 651}

Simplify the radical expression

\frac{1}{3 651}

Multiply by the Conjugate

\frac{3 65 1 ^{2}}{3 651 \times 3 65 1 ^{2}}
