Solve 25x^4=15 - ScanMath

Evaluate

25 x^{4} = 15

Divide both sides

\frac{25 x ^{4}}{25} = \frac{15}{25}

Divide the numbers

x^{4} = \frac{15}{25}

Cancel out the common factor 5

x^{4} = \frac{3}{5}

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

x = \pm 4 \frac{3}{5}

Simplify the expression

More Steps

x = \pm \frac{4 375}{5}

Separate the equation into 2 possible cases

x = \frac{4 375}{5} x = - \frac{4 375}{5}
