Question

log help!!!!!

Answer 1

in \[\log _{a}c=d\] which variable may at times be negative? A, C, D or none of the above

Answer 2

only D. this can be observed simply from the graph y = logx

for the base [a]. we know that to change the log's base on your calculator you do log(x)/log(new base) to get log(x) of the new base. to change to a negative base would imply that you could plug in a negative number in x which is wrong.

Answer 3

thanks.. do you know in which variable may at times be zero

Answer 4

@Euler271

Answer 5

again, for the same reasons, only d

Answer 6

okay do you know which variable can never be equal to one @Euler271

Answer 7

i think the base cant be negative for example
8= 1^x has not meaning if i apply log in both sides i get
Ln8= Ln(1)^x
Ln8=xLn (1) and Ln 1 is not defined

Answer 8

i know that but which variable cannot be equal to 1

Answer 9

i already told u
the base cant be 1

Answer 10

sorry in the last mensaje i meant the base cant be 1
instead of the base cant be negative

Answer 11

okay thats fine but is the base c or a?
