Question

what is the value of x if (3/11)^-4 × (3/11)^3x = (3/11)^8​

Answer 1

Step-by-step explanation:

$({ \frac{3}{11} })^{ - 4} \times ({ \frac{3}{11} })^{3x} = ({ \frac{3}{11} })^{8} \\ \\ ({ \frac{3}{11} })^{ - 4 + 3x} = ({ \frac{3}{11} })^{8} \\ \\ - 4 + 3x = 8 \\ 3x = 8 + 4 \\ 3x = 12 \\ x = \frac{12}{3} \\ x = 4$
