Solve 105 = 1/3 x (7 x x)*x 15

Evaluate

105 = \frac{1}{3} x (7 x \times x) x \times 15

Remove the parentheses

105 = \frac{1}{3} x \times 7 x \times x \times x \times 15

Simplify

More Steps

105 = 35 x^{4}

Swap the sides of the equation

35 x^{4} = 105

Divide both sides

\frac{35 x ^{4}}{35} = \frac{105}{35}

Divide the numbers

x^{4} = \frac{105}{35}

Divide the numbers

More Steps

x^{4} = 3

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

x = \pm 43

Separate the equation into 2 possible cases

x = 43 x = - 43

Solution

x_{1} = - 43, x_{2} = 43

Alternative Form

x_{1} \approx - 1.316074, x_{2} \approx 1.316074
