Question

$\sqrt[10]{3 {}^{15} } = \sqrt[x]{3 {}^{3} }$
qual valor de x?​

Answer 1

Explicação passo-a-passo:

$\sqrt[10]{3 {}^{15} } = \sqrt[x]{3 {}^{3} } \\ 3 {}^{ \frac{15}{10} } = 3 {}^{ \frac{3}{x} } \\ \frac{15}{10} = \frac{3}{x} \\ \frac{3}{2} = \frac{3}{x} \\ 3x = 3 \times 2 \\ 3x = 6 \\ x = \frac{6}{2} \\ x = 2$
