check my answer :D
Expand the logarithmic expression.
Log (base b) Square root 57/74
My answer: 1/2log(base b) 57-log (base b) 74 (the minus is because they are divided.

Hello,
your answer should be true if you put parenthesis!

=1/2[log base 9(57)-log base9 (74)]
=1/2 log base 9 (57)-1/2 log base 9(74)




Answer:

Yes the answer is correct explained in step-by-step explaination.

Step-by-step explanation:

Given the logarithmic expression

log(base b)square root 57/74

[tex]\log_{b}\frac{\sqrt57}{74}[/tex]

Now we know that [tex]\log \frac{m}{n} =\log m-\log n\\\log x^{\frac{1}{2} } =\frac{1}{2}\log x[/tex]

Hence, [tex]log _{b}\sqrt57=\frac{1}{2}log _{b}57[/tex]

∴[tex]log_{b}\frac{\sqrt57 }{74}=log_{b}{\sqrt57 }-log_{b}{54}[/tex]  

[tex]\frac{1}{2}log_{b}57-log_{b}54[/tex]
