Solve t*t^3-5 - ScanMath

Evaluate

t \times t^{3} - 5

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

t \times t^{3} - 5 = 0

Multiply the terms

More Steps

t^{4} - 5 = 0

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

t^{4} = 0 + 5

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

t^{4} = 5

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

t = \pm 45

Separate the equation into 2 possible cases

t = 45 t = - 45

Solution

t_{1} = - 45, t_{2} = 45

Alternative Form

t_{1} \approx - 1.495349, t_{2} \approx 1.495349
