More Steps

Evaluate

d \times d^{3} \times 357

Multiply the terms with the same base by adding their exponents

d^{1 + 3} \times 357

Add the numbers

d^{4} \times 357

Use the commutative property to reorder the terms

357 d^{4}

357 d^{4} - 100

Show Solution

d_{1} = - \frac{4 100 \times 35 7 ^{3}}{357}, d_{2} = \frac{4 100 \times 35 7 ^{3}}{357}

Alternative Form

d_{1} \approx - 0.7275, d_{2} \approx 0.7275

Evaluate

d \times d^{3} \times 357 - 100

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

d \times d^{3} \times 357 - 100 = 0

d \times d^{3} \times 357

Multiply the terms with the same base by adding their exponents

d^{1 + 3} \times 357

Add the numbers

d^{4} \times 357

Use the commutative property to reorder the terms

357 d^{4}

357 d^{4} - 100 = 0

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

357 d^{4} = 0 + 100

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

357 d^{4} = 100

Divide both sides

\frac{357 d ^{4}}{357} = \frac{100}{357}

Divide the numbers

d^{4} = \frac{100}{357}

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

d = \pm 4 \frac{100}{357}

d = \pm \frac{4 100 \times 35 7 ^{3}}{357}

Separate the equation into 2 possible cases

d = \frac{4 100 \times 35 7 ^{3}}{357} d = - \frac{4 100 \times 35 7 ^{3}}{357}

Solution

d_{1} = - \frac{4 100 \times 35 7 ^{3}}{357}, d_{2} = \frac{4 100 \times 35 7 ^{3}}{357}

Alternative Form

d_{1} \approx - 0.7275, d_{2} \approx 0.7275
