Solve r^512-46-1 - ScanMath

Question

Simplify the expression

12 r^{5} - 47

Evaluate

r^{5} \times 12 - 46 - 1

Use the commutative property to reorder the terms

12 r^{5} - 46 - 1

Solution

12 r^{5} - 47

Show Solution

r = \frac{5 30456}{6}

Alternative Form

r \approx 1.313964

Evaluate

r^{5} \times 12 - 46 - 1

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

r^{5} \times 12 - 46 - 1 = 0

Use the commutative property to reorder the terms

12 r^{5} - 46 - 1 = 0

Subtract the numbers

12 r^{5} - 47 = 0

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

12 r^{5} = 0 + 47

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

12 r^{5} = 47

Divide both sides

\frac{12 r ^{5}}{12} = \frac{47}{12}

Divide the numbers

r^{5} = \frac{47}{12}

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

5 r^{5} = 5 \frac{47}{12}

Calculate

r = 5 \frac{47}{12}
