She has to score at least 86 on her fifth test.

Further explanation:

We will use the average formula to find the fifth value.

Given

Average\ required=80\\x_1=81\\x_2=73\\x_3=84\\x_4=76\\x_5=?

We have to find x5

The formula for average is:

x=\frac{Sum\ of\ values}{Total\ number\ of\ values}\\Here,\\n=5\\So,\\x=\frac{x_1+x_2+x_3+x_4+x_5}{5}\\Putting\ values\\80=\frac{81+73+84+76+x_5}{5}

80*5=314+x_5\\400=314+x_5\\x_5=400-314\\x_5=86

She has to score at least 86 on her fifth test.

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
