Question

Solve log x = 4.Ox= 4Ox= 40Ox= 1,000Ox= 10,000Need help!!!

Answer 1

Let's recall that when do not see a base written, it means the base is 10.

Let's also recall that the log form and the exponential form are interchangeable.

`\log _{a\text{ }}b\text{ = c }\Rightarrow\text{ }a^{c\text{ }}=\text{ b}`

Therefore, we have:

`\log _{10\text{ }}x\text{ = 4 }\Rightarrow10^4\text{ = x}`
`The\text{ correct answer is x = }10^{4\text{ }}=\text{ 10,000}`

The correct answer is D.
