Question

Write y = 10x as a logarithmic function.
Answer

logx10 = y

logyx =10

log10y = x

logxy =10

Answer 1

@zepdrix B huh?

Answer 2

\[\huge y=10^x\]This is how the problem is SUPPOSE to look? :D

We gotta get you used to using the ^ symbol, and not just copy paste.. these are really difficult to read sometimes lol

Answer 3

So B right? I'll be more careful

Answer 4

If we want to rewrite it as a logarithm, the BASE of our log should be the BASE of our exponential term.

So in this case we'll have a log with base 10.
What goes INSIDE the log, is whatever is on the other side of the EQUALS sign.
And then we set the log EQUAL to the exponent that we had.

Answer 5

Am I right though?

Answer 6

It looks like we have a 10 for our base, we'll be stuffing Y inside of the log, since that's what's on the other side of the equation.
aaaand, we'll set that all equal to the exponent that we had, x in this case.

Giving us,\[\huge y=10^x \qquad \rightarrow \qquad \log_{10}y=x\]

Answer 7

So B can't be right?

Answer 8

B? Hmm, no this isn't quite what we want.
\[\huge \log_yx=10 \qquad \rightarrow \qquad y^{10}=x\]

Answer 9

What about C I got that as my 2nd option...

Answer 10

@zepdrix C try C!

Answer 11

@Spectrum HELP

Answer 12

@zepdrix I'll let you finish your question someone elses than I'll wait

Answer 13

@mathstudent55 COME HERE

Answer 14

@jamesaa I think C.

Answer 15

C looks right

Answer 16

Can you explain please.

Answer 17

Use the base of the exponent as the base
