Solve 18=6|9n^4| - ScanMath

Evaluate

18 = 6 9 n^{4}

Simplify

More Steps

18 = 54 n^{4}

Swap the sides of the equation

54 n^{4} = 18

Divide both sides

\frac{54 n ^{4}}{54} = \frac{18}{54}

Divide the numbers

n^{4} = \frac{18}{54}

Cancel out the common factor 18

n^{4} = \frac{1}{3}

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

n = \pm 4 \frac{1}{3}

Simplify the expression

More Steps

n = \pm \frac{4 27}{3}

Separate the equation into 2 possible cases

n = \frac{4 27}{3} n = - \frac{4 27}{3}

Solution

n_{1} = - \frac{4 27}{3}, n_{2} = \frac{4 27}{3}

Alternative Form

n_{1} \approx - 0.759836, n_{2} \approx 0.759836
