Question

What is

Y=log x If y=10, then what is x?

A.
10


B.
1


C.
100


D.
10^2

Answer 1

`y = log_a x\\\\x = a^y`


`10 = log_(10)~ x`

Therefore,


`x = 10^10`

Your answer is 10^10.

None of your answer choices match.

Answer 2

The answer would be none of the above since if y was = 10, then x would have to be 10^10. 

log x means what value you have to raise 10 to to get x, so if y = log x = 10, then x = 10^10
