Solve a^3a-200 - ScanMath

Evaluate

a^{3} \times a - 200

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

a^{3} \times a - 200 = 0

Multiply the terms

More Steps

a^{4} - 200 = 0

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

a^{4} = 0 + 200

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

a^{4} = 200

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

a = \pm 4200

Separate the equation into 2 possible cases

a = 4200 a = - 4200

Solution

a_{1} = - 4200, a_{2} = 4200

Alternative Form

a_{1} \approx - 3.760603, a_{2} \approx 3.760603
