Solution

More Steps

Evaluate

2 n^{2} \times n

Multiply the terms with the same base by adding their exponents

2 n^{2 + 1}

Add the numbers

2 n^{3}

2 n^{3} - 607

Show Solution

n = \frac{3 2428}{2}

Alternative Form

n \approx 6.720262

Evaluate

2 n^{2} \times n - 607

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

2 n^{2} \times n - 607 = 0

Multiply

More Steps

Multiply the terms

2 n^{2} \times n

Multiply the terms with the same base by adding their exponents

2 n^{2 + 1}

Add the numbers

2 n^{3}

2 n^{3} - 607 = 0

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

2 n^{3} = 0 + 607

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

2 n^{3} = 607

Divide both sides

\frac{2 n ^{3}}{2} = \frac{607}{2}

Divide the numbers

n^{3} = \frac{607}{2}

Take the 3 -th root on both sides of the equation

3 n^{3} = 3 \frac{607}{2}

Calculate

n = 3 \frac{607}{2}
