I rlly need help with this question! pls help and explain..thxs
GarryVolchara [31]

Answer:

Step-by-step explanation:

Recall these rules of logs:  log a + log b = log (ab), and log a^b = b log a

Then 3 log q = log q^3 and 6 log v = log v^6, and

log q^3 + 6 log v becomes log q^3 * v^6

Now rewrite this using b as the base:

log     q^3 * v^6

     b

Solve the equation. Check your answer. If necessary, round to 3 decimal places
Lana71 [14]

Answer:

x ≈ ±20.086/√(t - 1)  

Step-by-step explanation:

ln(t - 1) + ln(x²) = 6

Recall that lnu + lnv = ln(uv). Then  

ln(t - 1) + ln(x²) = ln[(t-1)x²] = 6

Take the natural antilogarithm of each side

(t - 1)x² = e⁶

Divide each side by t - 1

x² = e⁶/(t-1)

Take the square root of each side

x = ±e³/√(t - 1)

x ≈ ±20.086/√(t - 1)
