Question

f(x)=log5x
Value of f(1/25)?

Answer 1

Put \(\frac{1}{25}\) where \(x\) is.

Answer 2

\[f(\frac{1}{25})=\log 5(\frac{1}{25})=\log \frac{1}{5}=\log 5^{-1}\]

Answer 3

:/ My options are:
a. sqrt2
b. -2
c. -1/2
d. 1/2

Answer 4

Well then, I guess you have posted the problem incorrectly.

Answer 5

The problem is actually \[f(x)=\log_{5}(x)\]
But we are not supposed to solve this for @mathsux4real. What I said should tell him enough to be able to do this problem, unless he is unfamiliar with manipulating exponents.

Answer 6

I would guess that 5 is the base. But that is not the way you posted it.

Answer 7

You are right Mertsj. 5 is the base. My fault that I didn't post it that way.

Answer 8

I meant to type f(x)=log_5x
Value of f(1/25)?

Answer 9

@mathsux4real, what is so hard about this for you?

Answer 10

Got it. -2.

Answer 11

Great job!

Answer 12

Thanks guys
