ANSWER
b. x=10²
EXPLANATION
The logarithmic equation is:
[tex] log(x) = 2[/tex]
Note that this is the common logarithm, so it has a base of 10.
[tex] log_{10}(x) = 2[/tex]
Take antilogarithm of both sides to base 10.
[tex] {10}^{ log_{10}(x) } = {10}^{2} [/tex]
This implies that,
[tex]x = {10}^{2} [/tex]
