Solve 4=21(3x^4) - ScanMath

Evaluate

4 = 21 \times 3 x^{4}

Multiply the numbers

4 = 63 x^{4}

Swap the sides of the equation

63 x^{4} = 4

Divide both sides

\frac{63 x ^{4}}{63} = \frac{4}{63}

Divide the numbers

x^{4} = \frac{4}{63}

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

x = \pm 4 \frac{4}{63}

Simplify the expression

More Steps

x = \pm \frac{4 4 \times 6 3 ^{3}}{63}

Separate the equation into 2 possible cases

x = \frac{4 4 \times 6 3 ^{3}}{63} x = - \frac{4 4 \times 6 3 ^{3}}{63}

Solution

x_{1} = - \frac{4 4 \times 6 3 ^{3}}{63}, x_{2} = \frac{4 4 \times 6 3 ^{3}}{63}

Alternative Form

x_{1} \approx - 0.501972, x_{2} \approx 0.501972
