Solve r^450-700200-0

Question

Simplify the expression

50 r^{4} - 700200

Evaluate

r^{4} \times 50 - 700200 - 0

Use the commutative property to reorder the terms

50 r^{4} - 700200 - 0

Solution

50 r^{4} - 700200

Show Solution

50 (r^{4} - 14004)

Evaluate

r^{4} \times 50 - 700200 - 0

Use the commutative property to reorder the terms

50 r^{4} - 700200 - 0

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

50 r^{4} - 700200

Solution

50 (r^{4} - 14004)

Show Solution

r_{1} = - 414004, r_{2} = 414004

Alternative Form

r_{1} \approx - 10.87835, r_{2} \approx 10.87835

Evaluate

r^{4} \times 50 - 700200 - 0

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

r^{4} \times 50 - 700200 - 0 = 0

Use the commutative property to reorder the terms

50 r^{4} - 700200 - 0 = 0

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

50 r^{4} - 700200 = 0

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

50 r^{4} = 0 + 700200

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

50 r^{4} = 700200

Divide both sides

\frac{50 r ^{4}}{50} = \frac{700200}{50}

Divide the numbers

r^{4} = \frac{700200}{50}

Divide the numbers

More Steps

Evaluate

\frac{700200}{50}

Reduce the numbers

\frac{14004}{1}

Calculate

14004

r^{4} = 14004

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

r = \pm 414004

Separate the equation into 2 possible cases

r = 414004 r = - 414004

Solution

r_{1} = - 414004, r_{2} = 414004

Alternative Form

r_{1} \approx - 10.87835, r_{2} \approx 10.87835
