Question

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

Answer 1

$$
\tt \Large{
y=\log x\\
10=\log x\\
10^{10}=10^{\log x}=x\\
So,~x=10^{10}
}
$$
Does this make sense?

Answer 2

thats wrong

Answer 3

x = 1

Answer 4

Log(1) = 0

Answer 5

y = log x
10 = log x
10 = 10^x
x = 1

Answer 6

Log answers the question, how many zeros are in 10^10 if y = 10. The answer is 10. So x = 10^10.
10^x is not log x
if 10^x = log x then 10^(10^x) = 10 ^(log x)=x, which is not true

Answer 7

log(10)=1
log(100)=2
log(1000)=3
...
...
log(10^1)=1
log(10^2)=2
log(10^3)=3
...
log(10^x)=x

Answer 8

Do you see that? Punch in those numbers in a calculator and it will confirm (use base 10). This also means log(1)=log(10^0)=0
