Solve b^6-30-10 - ScanMath

Evaluate

b^{6} - 30 - 10

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

b^{6} - 30 - 10 = 0

Subtract the numbers

b^{6} - 40 = 0

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

b^{6} = 0 + 40

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

b^{6} = 40

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

b = \pm 640

Separate the equation into 2 possible cases

b = 640 b = - 640

Solution

b_{1} = - 640, b_{2} = 640

Alternative Form

b_{1} \approx - 1.849311, b_{2} \approx 1.849311
