Question

Calcule el valor de " " en : (8x + 7) ^ n = (7x + 12) ^ n

Answer 1

DESARROLLO:

$(8x + 7) {}^{n} = (7x + 12) {}^{n} \\ \sqrt[n]{(8x + 7) {}^{n} } = \sqrt[n]{(7x + 12) {}^{n} } \\ (8x + 7) {}^{ \frac{n}{n} } = (7x + 12) {}^{ \frac{n}{n} } \\ (8x + 7) {}^{1} = (7x + 12) {}^{1} \\ 8x + 7 = 7x + 12\\ 8x + 7 = 7x + 12 \\ 8x - 7x = 12 - 7 \\ x = 5$

RESPUESTA:

X = 5°
