Question

Which of the following expressions has the same derivative as y = log x?

Answer 1

a) \[\log \frac{ 1 }{ x } \]
b)\[3logx\]
c) \[\log_{6} x\]
d) \[\log 5x\]
e)\[logx ^{2}\]

Answer 2

hint: properties of log come in handy here

Answer 3

use the quotient rule for first one
use the product rule on d

Answer 4

is a log 1 - log x
and is d log 5 + log x

Answer 5

in this case, it should be d then, because log5 is a constant, and the derivative of a constant is 0

Answer 6

yep

Answer 7

ty, sorry bout that, both my algebra, and pre calc basics are a bit weak :(

Answer 8

in calculus is where we learn algebra for most of us

Answer 9

and trig

Answer 10

the calculus part is actually easy i think
