Question

Solve 3(10)^x = 30,000

Answer 1

Try to get x isolated on one side.
Divide by 3 on both sides.
(10)^x = 10,000
Count how many zeroes there are in the number 10,000. There are 4 zeroes, therefore 10 was raised to the 4th power to get to 10,000.
That means “x” is 4. Hope this helps :)

Answer 2

Answer: x = 4

Explanation:

We will need to use logs here...

First divide each side by 3

`3(10)^x=30000`

`10^x=10000`

Then take the log of each side

Keep in mind that
`log_(10) (10)` gets canceled out to leave x

`log_(10) (10^x)=log(10000)`

Finally, log(10000) = 4 because
`10^4=10000`

`x = 4`
