Best ResponseYou've already chosen the best response.3right ! now we use the definition of a log \[\log_b a = c\iff a=b^c\]

Best ResponseYou've already chosen the best response.3you had \[\log_2(x) = 2\] so \[x = . . . \]

Best ResponseYou've already chosen the best response.3Use the definition for example \[\log_{10}(A) = 3 \iff A = 10^3 = 1000\]

Best ResponseYou've already chosen the best response.0i dont get it, the computer says its .25

Best ResponseYou've already chosen the best response.1it's probably due to the confusion of the regular 2 being typed out and the subscript 2... .25 = 1/4 . so the computer claims that it's 1/4 > .25?!
