Solve r^52-1 - ScanMath

Evaluate

r^{5} \times 2 - 1

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

r^{5} \times 2 - 1 = 0

Use the commutative property to reorder the terms

2 r^{5} - 1 = 0

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

2 r^{5} = 0 + 1

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

2 r^{5} = 1

Divide both sides

\frac{2 r ^{5}}{2} = \frac{1}{2}

Divide the numbers

r^{5} = \frac{1}{2}

Take the 5 -th root on both sides of the equation

5 r^{5} = 5 \frac{1}{2}

Calculate

r = 5 \frac{1}{2}
