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

-x - 4 = 4x - 54 im to lazy to figure it out myself
BlackZzzverrR [31]

Step-by-step explanation:

  • <em>-x-4=</em><em>4</em><em>x</em><em>-</em><em>5</em><em>4</em>

Adding x on both sides, we get

  • <em>-x-4+</em><em>x=</em><em>4</em><em>x</em><em>-</em><em>5</em><em>4</em><em>+</em><em>x</em>
  • <em>-</em><em>4</em><em>=</em><em>5</em><em>x</em><em>-</em><em>5</em><em>4</em>

Adding 54 on both sides, we get

  • <em>-</em><em>4</em><em>+</em><em>5</em><em>4</em><em>=</em><em>5</em><em>x</em><em>-</em><em>5</em><em>4</em><em>+</em><em>5</em><em>4</em>
  • <em>5</em><em>0</em><em>=</em><em>5</em><em>x</em>

Dividing both sides by 5, we get

  • <em>5</em><em>0</em><em>/</em><em>5</em><em>=</em><em>5</em><em>x</em><em>/</em><em>5</em>
  • <em>1</em><em>0</em><em>=</em><em>x</em>

<em>Hence,</em><em> </em><em>the </em><em>value</em><em> of</em><em> x</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em>.</em>
