Question

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

Answer 1

x is 10^10

Answer 2

My teacher says the answer is 1, but I dont know how she got that.

Answer 3

\[\log(x)=10\] or
\[\log(10)=x\]?

Answer 4

what is the base of the logarithm here?

Answer 5

because if
\[\log(x)=10\] this means
\[x=10^{10}\] (assuming base is 10)

Answer 6

this question uses exponentials..

\[10^y = 0^{\log x}\]
then by log laws

\[10^y = x\]

if y = 10 then \[10^10 = x\]
