Evaluate

15 = 8 x^{3} \times 3 x^{4}

Multiply

More Steps

15 = 24 x^{7}

Swap the sides of the equation

24 x^{7} = 15

Divide both sides

\frac{24 x ^{7}}{24} = \frac{15}{24}

Divide the numbers

x^{7} = \frac{15}{24}

Cancel out the common factor 3

x^{7} = \frac{5}{8}

Take the 7 -th root on both sides of the equation

7 x^{7} = 7 \frac{5}{8}

Calculate

x = 7 \frac{5}{8}
