## anonymous 5 years ago Please answer this for me!! y = log x If y = 10, then what is x?

1. anonymous

$\log_{x}a = b \rightarrow a = x ^{b}$

2. anonymous

so, $\log_{10}x = y \rightarrow x =?$

3. anonymous

Raise 10 to the power of both sides of the equation.

4. anonymous

is this right? y = log x 10 = log x 10 = 10^x x = 1

5. anonymous

10 = log x so x = ? follow the logic of what I posted earlier.

6. anonymous

10*10

damn

x=10^10.............any dobt in this...!!!

$\log _{a}X=Y where X=a ^{Y}$ First guy wrote it the right way but he used X and Y in a different way which can confuse you. Also if not told in the question. a =10 and you know Y= 10 so just plug it in.

thanks i think i get it now
