Question

What is the solution to log^2(9x) -log^2 3=3

Answer 1

Answer:
`\bold{B)\quad x = (8)/(3)}`

Explanation:

`log_2(9x)-log_2(3)=3\\\\\\log_2\bigg((9x)/(3)\bigg)=3\qquad\qquad \rightarrow \text{used rule for condensing logs}\\\\\\log_2(3x)=3\qquad\qquad \rightarrow \text{simplified}\\\\\\3x=2^3\qquad\qquad \rightarrow \text{used rule for eliminating log}\\\\\\3x=8\qquad\qquad \rightarrow \text{simplified}\\\\\\\large\boxed{x=(8)/(3)}`
