Question

Solve log x=4

x=4
x=40
x=1000
x=10000

Answer 1

Answer:10000

Explanation:

Remember that log x and 10^x are inverse functions.

If you have log x = 4 and want the value of x, write this out:

log x 4

10 = 10

This simplifies to:

x = 10^4, and so the fourth answer choice is the correct one.
