Solve dd^3-1666 - ScanMath

Evaluate

d \times d^{3} - 1666

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

d \times d^{3} - 1666 = 0

Multiply the terms

More Steps

d^{4} - 1666 = 0

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

d^{4} = 0 + 1666

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

d^{4} = 1666

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

d = \pm 41666

Separate the equation into 2 possible cases

d = 41666 d = - 41666

Solution

d_{1} = - 41666, d_{2} = 41666

Alternative Form

d_{1} \approx - 6.388792, d_{2} \approx 6.388792
